wal_level not changing

Hi,

update pg_settings set reset_val='minimal' where name='wal_level';

ERROR: parameter "wal_level" cannot be changed without restarting the
server

set wal_level='minimal';

ERROR: parameter "wal_level" cannot be changed without restarting the
server

update pg_settings set setting='minimal' where name='wal_level';

ERROR: parameter "wal_level" cannot be changed without restarting the
server

Even after restarting and reloading the server multiple times the setting
does not update and remains as below:

show wal_level;

+-----------+

| wal_level |

+-----------+

| replica |

+-----------+

Thanks & Regards,
