Do I REALLY need to release fuel pressure before replacing intake manifold?

So here is my problem. I started the process to replace my driver's side valve cover gasket so I have disconnected all my spark plugs and coils and a bunch of hoses etc. to set the wiring harness aside so I can get the cover off.

Well, now I am ALSO going to be replacing my intake manifold at the same time. My question, if I didn't shut off the fuel and then run my car until it dies, do I REALLY need to put everything back together just to do that before I pull off the fuel rail. It might be worth noting that my car has been sitting for about 10 days... Or is there another way I can somewhat easily release my fuel line pressure?

I replaced my intake manifold recently and forgot to run it out of fuel.
As I recall there was a bit of pressure in the system and some fuel came out but not enough to worry about.
Mine had only sat for a day.
Thanks, I do have a new fuel filter I was planning to replace as well, maybe I'll just do that first because it's in an easier spot to control a gas spray 😂
