Upgrade my razer blade 15 2020 RZ09-0328 PCIE from gen 3 to gen 4 thanks to the bios or anyway else?

Hi everyone,

I wanted to know if there is anyway to upgrade or activate via the bios by disabling SATA ports the PCIE gen 4.0 * 4 on my Razer blade 15 2020 RZ09-0328X in order to read/write faster than 3 Gb/s (since my SSD can read/write 7 Gb/s)?

If anyone has any idea, I’m volunteer to listen to it.

By the way I don’t manage to upgrade my bios from 1.04 to 1.06. Am I the only one? Is there any trick to follow to manage to update it?

Thanks a lot to everyone for your time to read this post!
