There is no hidden advanced mode and no setting that will let you switch PCIe mode.

Hi, @VasuOberoi 

 

Maybe this related Dell notebook article will be of help to you...

 

Solved: XPS 9560 NVMe drive only running with two lanes of PCIe - Dell Community

 

I may be wrong, but it is my understanding that if a M.2 slot supports both SATA and NVMe drives as in the 15-da1xxx model series, the NVMe drive transfer speed is slower than in a M.2 slot that exclusively supports NVMe drives.

NOW IT SAYS THE FIX IS TO REMOVE SSD AND REINSERT it in M.2 slot and after this change power mode and sleep settings then it should work fineat full speed (32 gb bandwidth).I WILL definitely try this and see if it works for me.BUT I WANT TO ASK a question.PLEASE REPLY

You're very welcome.

 

You will not need to reinstall Windows. 

 

There should be no data loss since you will be doing this with the power and battery removed like when you originally installed it.
