Seeing the following error with every update with mysql disabled:

=> Log closed Wed Oct 3 10:02:17 2018
=> Log opened from cPanel Update (upcp) - Slave (3935) at Wed Oct 3 10:02:17 2018

mysql is not necessary in our configuration and consumes too much memory if running solely to silence these daily update errors.

Hello Paul,

Internal case CPANEL-21494 addresses the issue where cPanel updates fail when MySQL is disabled. The solution is published to cPanel & WHM version 76 (currently available on the EDGE release tier):

Fixed case CPANEL-21494: Don't perform MySQL connection check when MySQL is disabled.

You can monitor the following page to see when version 76 reaches each release tier:
