Prevent External Drives from Sleeping in Tahoe

I use Logic Pro and since many years I keep Logic's Sound library (172GB) on an external HDD. Up to Sequoia I have used the app Amphetamine and it has kept my HDDs (yes I have a few more) from going to sleep. However Amphetamine does not seem to work at all in Tahoe. The HDDs constantly go to sleep. I have contacted the developer but no reply. There is a Terminal command, ”sudo pmset -a disksleep 0”, that I will try if nothing else comes up.

Any ideas?
