Is it possible to apply modifiers to resistances in the same way you can with weapon upgrades like Bullet Damage, Shotgun Shell Damage etc?

Do I gather from the rather awkward silence that that is a no?

If it's not documented then I don't think it currently exists. You can put in a modding interface request for it though and see what the devs say

This currently doesn't exist.
It was asked for few times already without dev response I think.
(Similarly ability to mod range of turrets)
