NVMe SSD Problem on Sf314-54g I can't even set the nvme mode on the BIOS, so what should I do?

Hi,
I've replaced the internal M2 SSD with a M2 NVMe 1tb WD Blue SSD.
I've cloned the old one to the new one and booted Windows.
Well, Windows is working slower as ever now. It freezes and keep stucking (before the replacement it was smooth).
I've also tried a fresh Windows install with no results.
If I do some benchmark I see that the SSD performs like 5 times lower than it should, it is a compatibility problem with the laptop?
Because everything it's locked up by Acer I can't even set the nvme mode on the BIOS, so what should I do? Switch to a M2 SATA SSD?
Officialy the NVMe SSD should be supported…
