Has anybody eliminated the bypass hose between the intake manifold and the water pump if so how do you go about doing it

Why would you want to do that?
I know they are a pain when removing the manifold, but the coolant flow works well as designed, why change it?

I plugged mine. Just tapped both ports and put pipe plugs in.
I don't run a thermostat so no bypass is ok but if you plug it i wouldn't run a thermostat.

If you do plug it and keep the T-stat at minimum drill a few 1/8 holes in the stat ring.

I haven't done it with the Ford 460 since it has no cooling problem, but I did it with a 400 Oldsmobile that had difficulty staying cool in the summer. I plugged it's bypass and omitted the thermostat. That helped with the cooling noticeably. If you don't want to do the tap & plug route you can buy rubber caps (Dorman?) and use them with hose clamps.

But, what is the advantage of plugging it?
What do you gain?
In my case i don't use a heater in this rig and don't use a thermostat.

Soooo.... i removed a potential leak point by plugging and it's easier removing the intake.

Yeah, I guess - LoL. But it,s brand new again (I have the manifold off pretty regularly) and I'm gettin old and the old Mustang only does a hundred miles or so a year anyway, so it'll probably pop for the next owner!
Interesting idea though. Might do it just for fun. Lock-down is already getting really tedious.

eng will run around 5 to 10 deg cooler, all it really does run hot water back into the intake, 5 to 10 can make a big diff.

I was always taught the bypass hose flowed water from the intake to the low pressure side of the pump.

And reducing the pressure in the manifold passage helps keep the thermostat bulb in coolant - not in air or vapour.
