Just noticed under System -> Tunables there are four entries added, of which I never created myself.

What are these, exactly? The most I could find about them is they have something to do with Fibre Channel adapters. But what does that have to do with a TrueNAS system that has no such devices? Can these entries be safely deleted? Was this a default introduced in a recent TrueNAS CORE 12.x update?
EDIT: Looks like someone else noticed too and beat me to it! (Still no explanation why these entries were added under-the-hood, though.)

Tunable hint.isp.N.role
Hello, I noticed that sometime between my original update to Truenas 12.0-U4 and the current verion 12.0-U7, tunables hint.isp.N.role where N=0-3 were added to my system. My understanding is that these are for fiber channel support which I do not use or have. Should I delete these tunables...
