IDK haven’t happened to me but then again I don’t use it that often. What kind of clipping?

The character's throat clips through the collar of the armor. So the character, has random bits of black and grey metal in the neck. This happens when the helmet off setting is active.

This seems to be the only armor that acts up. Odd because all the other armors cling more tightly. I thought the character's neck was too thick. So i altered neck size to the lowest setting. Didn't help

You answered your own question ”Is there any fix to this” with toggle helmet

Under helmet setting there's two options helm on or helm off. What's the point in having options; If helm off ain't working right?

This seems like a sloppy design choice.
