no attack and no skill

[xmaniacx]

is there a way to disabled attack and skill when equipping that certain items?

I think so, yes. If you search for the script that is activated upon "overweight" status, you should be able to insert that same string into an equipment script slot.

Although, I could be wrong about that since I haven't tried it out personally. If it works, be sure to edit the script so natural healing doesn't get affected.
