Drilling out hardened steel screws question
If regular HSS won't do it, cobalt won't either.

More thoughts.
A cobalt bit or try a reciprocating saw with a long, fine
tooth, bimetallic blade. If the bimetallic blade won't cut
the screws, get a diamond blade. Just lift the board enough
to get the blade under it and cut off the screws.
