Is PCIE x4 bootable for NVMe SSD under Linux

[Bullet64]

Yes, i have remove the resistor on preproduction rockpro64!!!! Please take care, that is not without danger!

My resistor has removed a specialist.

After this on NVMe Card the red LED is ON And the NVMe card works.

On the SATA-Card is an white(?) LED. But this LED isn't ON. So maybe wrong pcie-regulator ???
