Asus rog trix does not see M.2 SSD

[8mile]

So. I bought a 2019 GL731GW. There seem to be a lot of issues with adding/replacing a M.2 SSD. Looks like some will work and some will not work(laptop does not see some M.2 SSD models at all)

I tried a 1TB Hynix GOLD M.2 SSD (2020!). Did not work. I put it in a 2015(!) Maximus Hero 8 where i could see it and also being able to install a windows version on it after some changes in the BIOS...looks like Onboard Devices Configuration (Auto, X2 Mode of X4 Mode) had a impact. The GL731GW has very few BIOS options so that likely will not float.

Looks like i can try disable TPM/secure booth after that i am likely out of options. Any other tips i could try?

My questions  here is what M.2 SSDs actually do work with these model series?

Disable the VMD controller in the BIOS.

ok. There is non such option in the BIOS. There also does not seem to be a hidden BIOS menu on these ASUS laptops. 

btw as it is there is a INTEL SSDPEKNW010T8 for W11 (which seem to be standard in this model). I added a Samsung 870 EVO SSD for storage. All this works fine. So looks like VMD controller is not present or if hidden is turned off.

I installed Windows 11 on the 870 SSD, removed the Intel M.2 after that, replaced it with a 1TB Samsung 980 M.2, installed Windows 11 on it, removed all data from the 1TB 870 SSD. So for the moment i use the M.2 980 for Windows and SSD 870 for storage.
