Really? I'm not doubting that you found this provision somewhere, but I
don't recall it. Mind giving a chapter and verse?

And I think that if the provision exists, the "certification" (again,
chapter and verse) would be by an instrument repair facility, not an
avionics facility.

Legally, if you disconnect the lines they must be recertified by an
avionics shop. Not even an A&P can disconnect static lines.
