Hello team,
I am trying to upload version 4.2.2+. On the Server Checks page it states that version 10.67 of Mariadb is requires and I am running version 10.4.31.
How do I resolve this issue?

Not really an issue but is server administration outside of Moodle. 
How, exactly, depends upon where/how hosted (might not be allowed to upgrade in that case) and platform (Windows/Linux/Other?).
However, MariaDB folks do have a doc:
One word of caution: before you attempt upgrade to MariaDB, do a site backup - that's and archive of code + a DB dump + minimally moodledata/filedir.

I'm just going to re-iterate what Ken says. I've not had good experiences upgrading MySQL and Mariadb with the data in place. I would recommend dumping the data. Upgrading the the software and then re-uploading the database. If it did work without doing that, you got lucky but it's *vital* to have a good backup of the database.
