There is no need to update grub anymore if you switch to a most recent kernel.

According to comment# 1013 in bug report it is now fixed:

I haven’t checked this thread in a long time, but I thought I should
post my findings just in case it is of any use to anyone.

A low end computer powered with an Intel N2807 which never worked more
than 30 mn without crashing when I didn’t set …max_cstates=1 now
works perfectly well with a stock kernel v. 5.3.1 or 4.19.75. I ran it
for a couple of days with each version without any issues. The average
power consumption was also down by a little over 10%.

It has taken about four years to fix this bug first reported December 8, 2015.
