Thanks for this method, unfortunately it didn't work with rEFInd, only once Debian is launched, but it is still useful as it will probably be useful at some point.Up to you. Reviewing notes from a couple years ago, I found one more thing you can try, as you were able to get Grub working.
There's a mechanism for disabling secure boot for Linux only, leaving it active for Windows. The command is sudo mokutil --disable-validation. Will request a one-time password to confirm the change. Use something super simple, like eight ones (11111111). Reboot. At the MOK screen, first tap any key to cancel countdown timer. Read instructions at leisure. Should be a button to click to proceed. Will ask for the one-time password; or maybe the X, Y and Z digits of said password (the reason for making them all the same). At next prompt, confirm to disable secure boot. Reboot (again).
To confirm, open Terminal and run mokutil -sb-state. You’re looking for, “SecureBoot enabled, SecureBoot validation is disabled in shim.” Boot Windows; confirm secure boot is working for purposes of one of the games requiring it. Boot to firmware settings; move rEFInd to top of the boot list. Confirm whether that works. If not, you can revert the change with sudo mokutil --enable-validation; same password drill as for disable.
Frankly, I probably wouldn't bother with this procedure just to get rEFInd working. Getting secure boot out of the way across the board (Linux-wise) would be worth it to me. YMMV.
