Well, the one below the heater valve outlet (from the hardline to the block) is a PITA, but it, in theory, can be replaced without removing the intake. I gave the matter some serious thought, though. You have to have really small hands and really thin forearms; I used a child. And removed the running board, mudflap, wheel and inner fender liner.
The hose from the the number 3 radiator outlet (the one everyone breaks when they lean on the radiator) runs from front to back under everything, but it's on top of the valve cover. Mostly.
Other than than, not that I'm aware of.
The fuel filter is another PITA under the intake. I used a child for that, too.

Many things are 'possible' but I can't imagine replacing the hoses with the intake on the vehicle.
There are about a dozen hoses total that go to the intake and at least 10 of them are not easy to reach. Additionally, if they've never been changed, some of them will be on there pretty tight and others connect to fairly fragile plastic fittings.

This^ plus removing the upper half of the intake allows better access to the coolant hoses mentioned before. I'm 6'1" and have fairly thin forearms and I still don't think I can reach every hose on the engine without removing some stuff. Just the way it is.
Not "child labor" but quality time spent with a youngster and skill sharing!
If you take the vertical support bar off the driver side of the intake, and remove the blue gas vapor control valve from under intake, you can reach all those vacuum hoses under the intake, on a 96-97 at least.
I recently replaced / added external VSV valve with intake on in an effort to take care of p0401. After all that time fumbling around and feeling under the intake, I should have just taken it off which is what I will end up doing when I get more parts to do the heater control valve and PHH while I have the intake off.

You didn't use a child, you used the skills of a future mechanic.

Great pictures by the way! Side question, the red-ish /orange and dark blue plastic plugs with wires comin out of them, what do they do specifically? Do you know?
Those boogers are the reason a lot of people have P0401 codes. That was what was wrong with mine, green/blue one was toast.

In the process now of reassembling the throttle body/upper intake manifold; and because the hoses are still original from ‘97, this one broke and I cannot reuse the old one anymore. What’s your recommendation for an alternative hose? Link to purchase? Or specs maybe that I can get from a hardware store?
Thank you in advance.

Bulk vacuum line:
The dealer will either have it on the shelf, or can get it next day. Use aftermarket substitutes at your peril.

If that's the rear TB coolant line:
The front TB coolant line is:
The dealer may have these in stock as bulk hose, but they will be able to get the correct length hose next day if they don't.

My intake is off now as I’m putting new injectors in. Can this cluster be deleted if the whole EGR system is gone ? I plan to vent the fuel tank into the frame through a filter and the charcoal canister. So, there’s really no purpose behind all of these vacuum switches any longer, correct ? ? I’ll cap the little and big nipple off, of course. Gonna throw it all back together today. Expert advice much appreciated.

a similar question: once the EGR system has been removed, can the blue switching valve also be removed entirely without affecting EVAP (it would seem so)?
and if so, could that side of the harness possibly be depinned and removed as well?
I'm in the middle of replacing all that stuff, and am suddenly wondering why, since the EGR system is never being reinstalled.
[EDIT] I yanked it.
