Hello, @Hussam1 

Thank you for reaching out to us.

Taking the example of the PRIME X470-PRO, if there is any bandwidth or related specification sharing between the M.2 and PCIe channels, you can find relevant annotations in the manual.

For the ROG STRIX X670E-F GAMING WIFI, the manual doesn't provide such indications. 
Thus, you can occupy both M.2 slots without impacting GPU speed or bandwidth.

Thank you.
