rocky supplies mariadb-server-10.3.35 for mysql on Rocky 8.8.
this may not be what you want, if you want a genuine oracle mysql with the support that comes with, and in that case I would suggest looking at Oribles web site and installing the version for Rhel 8 or 9 as appropriate.
I use the above Mariadb and for my requirements its 1 to 1 equivalent to Mysql.
