That's possible. Here is the official documentation:

https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/bootflow.md

Booting requires a MBR partitioned disk, or at least a hybrid MBR that
lets the boot code find a FAT partition.

That's what I do. The SD card has the small FAT partition with bootloader,
kernel and a few config files, and the SSD has the system and uses
GPT partitions.
