[johnnync21]

Hello,
I buy the new Xiaomi mi laptop Air i7-8550u.
I can boot but I can't erase my pm961 ssd.

I can boot but I can't erase my pm961 ssd.

Is there a specific error message you have?

Note: PM961 has been reported as having serious issues with Apple's NVMe kext.

Sorry. I just realized that I have the PM981.. I can erasiDisk with terminal but I have some bootloops.
PM981 NVME SSD can be recognized no matter nvmexpressdxe.efi is put in the driver64uefi folders or not. However, it's recognized as external drives by the Disk Utility even if I applied the Piker R. patch#external as instructed in his blog.

Not sure PM981 has good compatibility either.

Can I change PM981 to 970 evo?

No experience with either.
The only NVMe I have tested with is Samsung 950 Pro.

Note: I have a WD Black WDS256G1X0C-00ENX0 that I have yet to start testing.

I guess you're lucky.
Lot's of reported problems with the PMxxx series.

In fact, all (non-Apple) NVMe devices are a bit of a gamble and suffer from various problems.

970 evo is total compatible

Not really. All non-Apple NVMe will be lacking power management... that particular puzzle has not been solved, AFAIK.
