CentOS - Aug 2020 - Cannot update grup2-common

when I try:
# dnf update grub2-common
Last metadata expiration check: 0:50:01 ago on Thu 27 Aug 2020 02:27:52 
PM CDT.
Error:
 ?Problem: The operation would result in removing the following 
protected packages: kernel
(try to add '--allowerasing' to command line to replace conflicting 
packages or '--skip-broken' to skip uninstallable packages or
'--nobest'
to use not only best candidate packages)

...so how should I proceed?

TIA,
Frank
