That's not going to happen. There will not be 60 votes to get past a filibuster in the Senate and Biden wouldn't sign it anyway. An override would require 67 votes.
I just bought this RF 10.5” in 5.56.
I know I can’t put a vertical grip under the guard without the “Stamp”, but is an AFG ok?
Yes, you can use hand stops and angled foregrips, but no vertical grips. FWIW, verital foregrips are defined as a grip with a 90° angle to the handguard, so some people like to live dangerously by using the BCM forward grip which has an angle that isn't quite 90°. Not sure I'd recommend doing that.
Do not do anything as has been stated.

I will add a Sig optic and some Magpul folding sights, plus the AFG.
No vertical grip, no can, no light, no laser.
