How to config checkQuorum to false for raft-rs?

[KunPengRen]

Problem: the leader node will be stuck and constantly compete to become to the leader when it can not receive the Quorum from followers in time.(my follower nodes face a high requests rate from clients).

Reason:
I check the reason is checkQuorum is set as true. So do the maintainer know how to set checkQuorum to false when starting the RAFT nodes?
