MySQL: avoid migration on startup

Hello there!
I’m trying to run Grafana while using a MySQL database.

Due to some particularities of the MySQL database (Percona cluster) and rights of the MySQL user, I cannot let Grafana start and perform its own migration to create the schema (tables and stuff).

I can and did, however, provide grafana with a mysql endpoint with a schema already created.

Is there a way to start tell grafana to start without performing migrations on its own? I tried consulting but migrations don’t seem to be mentioned.

EDIT: for the sake of clarity: the schema I’m trying to use has been created with grafana on another, less locked down mysql database and then imported into the percona cluster database. In terms of tables and relations, it’s identical to what grafana would create with its own migrations.

Any help is welcome.

Thanks in advance,
