Is possible to make any of the 4 fundamental forces weaker or go to 0 in any situation?

You can shield E&M fields

Also neutral things don't experience e-m.

This is not so simple that such a blanket statement applies. Neutrons, for example, have a magnetic moment. You can induce dipole moments in neutral atoms.

Strong nuclear force goes to zero when distances become very small (asymptotic freedom); electromagnetic forces go to zero at very large distances (inverse-square-of-distance for electrostatic forces, and inverse-of-distance for radiation).

I'm not sure that's what you're looking for though. You may be asking about something like shielding.

EM can be shielded, as Swansont said.

Strong force cannot be shielded at any distance range where it's sizeable, due to its complicated polarity.

Gravity cannot be shielded either, due to not having any polarity at all.

Weak force is not at all about shielding. It's a very different kind of force having to do with decay (plus neutrinos cannot be efficiently shielded).
