How to stop scheduled jobs in Metabase test environment

We restore the Metabase production database in the test environment for testing. Our production DB has several scheduled batch jobs for mailing reports to customers. I clear SMTP settings, but running these batch jobs creates an additional burden on our source database. Is there any way I can disable all scheduled batch jobs in the testing environment

You should start your Metabase test server with blank environment variables in the server

Thanks for the quick response. Can you please elaborate on which environment variable should keep blank?

all that have to do with smtp

I already cleared SMTP settings. Good to know that if there are no SMTP settings, Metabase doesn't run the scheduled jobs.
