We have installed magento 2.3.4 with parcona xtraDB cluster and we are getting error on cron run

main.ERROR: SQLSTATE[HY000]: General error: 1105 Percona-XtraDB-Cluster prohibits use of GET_LOCK with pxc_strict_mode = ENFORCING, query was: SELECT GET_LOCK(?, ?);

Hello Rupeshgardi,
The error message you are receiving is quite self-explanatory. The function GET_LOCK() is not allowed in PXC while the cluster is in ENFORCING mode. Your options are to change pxc_strict_mode=PERMISSIVE, or modify the behavior of the application to stop using GET_LOCK() functions and use more app-native locking.
The reason this function is prohibited is because this function is not cluster-wide. If your application executes GET_LOCK() on node1, another connection on node2() can acquire the same lock without conflict. If you are certain that your application is isolated to 1 node, then you should feel safe in turning off this protection.
