Move RootFS on Radxa Rock 4 SE?

Hi!
Is it possible to move RootFS to a NVMe drive (hat) on the Radxa Rock 4 SE? No option for it in drive_manager.

I boot from a 16GB eMMC but would like to move RootFS to the NVMe drive, since this SBC doesn’t have SPI and can’t boot from the NVMe natively.

DietPi v9.19.2 on the SBC.
