Solved!
"UEFI Boot" is really a fantastic tool: I didn't notice the "Boot Maintenance Manager" item, which allows you to add an entry in the grub, navigating along the same path I found using the "EFI Shell"! It is now possible, from "UEFI Boot", to customize the Grub menu, also setting the boot order, then using Raspberry Pi Imager [Misc utility images > Bootloader (Pi 4 family) > SD Card Boot] to configure the boot from microsd, instead of usb. Everything perfect now!
