press the key that opens the machine firmware (used to be called BIOS, but it isn't really any more), usually F2 or Del. Then look at the boot menu provided, and select the UEFI version of the install media to boot. That will boot it in EFI mode, and it will install in EFI mode.
Does that mean that the install media should appear in my uefi boot menu as (at least) two entries? Or are we talking about the grub menu that appears *after* booting from the flash drive?
If you have legacy (CSM) mode enabled, then likely you will see an entry for both, one UEFI and one legacy. This is the system boot menu, not grub. Once you get the grub menu, the mode has already been determined.
After booting I can confirm whether the install media is in uefi mode by checking if /sys/firmware/efi exists, right?
Yes.
