Can i use qan only? except other exporters like mysqld_exporter

i have been using mysqld_expoter and cloudwatch_exporter in my monitoring environment.
and now, i want to use PMM qan.

so i installed pmm-admin, and added mysql.
but it seems pmm automatically run mysqld_exporter and mysql_perfschema_agent ( for slow log qan )

i want my mysqld_exporter and cloudwatch_exporter to use the existing environment
and only qan to be used in the new environment.

how can i shutdown mysqld_exporter which is implemented automatically by pmm-admin
or how can i implement only qan except mysqld_exporter

pleas help
