"Romex Behind Fire Rated Walls"

In examining my circa 1962 Square D split bus breaker box, I notice that a few circuit have "Romex" style non metallic sheathed cable coming out the sides and top of the breaker box before going behind the suspended ceiling with lift out tiles.

I notice that the NEC manual seems to require non metallic sheathed cable to be behind fire rated walls and ceilings. Does a suspended ceiling meet that specification?

Is the nonmetallic sheathed cable coming out the sides and top of the breaker box wrong? If so, can I build a removable wallboard wall around the breaker box?

What would be reasonable ways to deal with this?

The 15 minute fire rating requirement is only for non-dwelling units. NM cables above a suspend ceiling is permitted for dwellings.

In my area NM cable coming out of the top/sides of the panel is OK
