Can a QO324L125G, which is a Main Lugs load center, be converted to a Main Circuit Breaker load center?

This load center is a Fixed Mains device, meaning that a Main Breaker Kit cannot be applied. However, a 3-pole QO or QO-VH branch circuit breaker, up to 100 ampere maximum, could be back fed as a Main Breaker. You would be required to also install a PK3MB Retaining Kit. The back fed circuit breaker would use the top, left three branch breaker spaces. You could also consider applying a separately mounted breaker in an enclosure to feed the Main Lugs load center.
