Hi. I use Clover rEFInd GRUB2 on my USB-HDD. I would like to use the means of loading ISO files not from the standard E2B menu, but directly to the ISO file from the rEFInd menu using grubfmx64.efi, but with different configuration files. Is it possible to run grubfmx64.efi with some parameters to indicate a different boot configuration file? Or what can you think of in my case?
