Bush-type summer squash are the least tolerant of borers, as unlike runner squash, they

have solid stems which less likely to be completely destroyed by borers.

There is a vining summer squash called "Tatume" that has solid stems and
is not bothered by borers.

One vine can totally take over your garden; they branch out, and each
branch can run 15 or 20 feet. I haven't grown them in a few years, I
may plant them again next year.
