Change configuration without restart node

Is it possible to turnoff the wsrep_debug without restarting the node ?
Actualy here is the configuration

mysql> SHOW VARIABLES LIKE 'wsrep_debug';
| Variable_name | Value  |
| wsrep_debug   | CLIENT |
1 row in set (0,00 sec)


Thanks in advance.

I have juste use

 SET GLOBAL wsrep_debug=NONE;

it seems good

Correct. As This parameter is dynamic, you can set it on the fly with the “SET GLOBAL” command without restarting the database.

Option Description
Command Line: –wsrep-debug
Config File: Yes
Scope: Global
Dynamic: Yes
Default Value: NONE
