Intel RST VMD Controller A77F - Driver version 20.0.0.1038 Poor Performance

[vendor1usa]

The system won't roll back to the 4/13/2023 driver which had my Samsung SSD 9100 Pro & Samsung SSD 990 EVO Plus running at max read and write speeds over 7,000 MB/s.  This new driver only has the drives reading and writing at 5,243 for the 9100 Pro and 5,353 for the 990 EVO. My computer is an Asus TUF FX608JHR with Intel i7-14650HX 64MB RAM running Windows 11 version 25H2 build 26200.7171.  Is there a way to attain the old driver so I can manually install?  Running the Setup.exe won't replace the driver.  PLEASE HELP!
