The question regarding ceramic bearings was covered here and the general view there is a much better way of spending your money.
In some cases regarding noise from a BB30 is not so much the bearings but how the housing of the bearings sits within the bike frame.
A quick test is on bearing wear is to hold the cranks and try to establish play by holding each pedal and moving the pedals laterally.
If there is slight play, you may be able to increase the pre load which may remove the play. Plenty of videos relative to your BB.
Worst case the bearings require replacement, it’s relatively straightforward and again plenty of videos on how to. Hambini and parktool are pretty comprehensive and cover most outcomes.
