Helios 300 PH315-54-70LH not recognizing M2 SSD

Hello there...

I'm having a big issue here, I updated my laptop BIOS through the official .exe app to do it, it was at 1.14 and upgraded to 1.15, but right after that, when I tried to turn my laptop ON again in the following day, my laptop wasn't booting, taking a really long time with just a black screen and then got a "No bootable device". Accessed the BIOS and my 2 M.2 SSD's (one with the Windows and another with just NTFS format storing games and stuff) are not showing up anymore.

Tried the SSD's on another laptop and they're just fine...

Please, can someone help me?? I really need this laptop, it was my gaming, study and work laptop, literally everything. The other laptop I have here is really old, it even has only 1 old M.2 slot that surprisingly recognizes PCIE3.0, but the other specs are just terrible, I'm a developer and need a really good laptop to run my code and emulators.

The only thing I changed is the BIOS and with the correct software, no power problems during bios flashing (I even have the battery charger connected to a no-break to ensure no problems with my work stuff).

Already tried rollback to 1.14, but it still don't recognize the M.2 PCIE slots. Wifi card works just fine and SATA plug works as well

    Also tried some stuff I found here, like unplugging batteries, power button for 30+secs, reinstalling SSDs, plugging batteries again. BIOS factory reset, checked RAM cards, etc. Literally everything is just fine, except for the M2 stuff. The light on the SSD even turns on, but it just gets warm and BIOS don't recognize them somehow

    How exactly did you update BIOS with "the official .exe app" and you can't roll back a BIOS version, Windows security won't allow that, did you reset BIOS or flashed a BIOS file with a USB flash drive? What SSDs have you installed, You state "Wifi card works just fine" and :"SATA plug" works as well, if you can't boot to Windows how can you check the Wi-Fi card and what "Sata plug", do you have a 2.5" Sata HDD/SSD installed, if so disconnect the 2.5" Sata drive and try to boot again? What Sata mode is set in BIOS. RST-Optane or AHCI?

    Downloaded the .exe bios updater for 1.15 from Acer support page (Drivers/BIOS/Softwares).

    I did the rollback with a usb flash to 1.14 (it worked just fine, but the PCIE still not loading the M.2 SSD's).

    I can boot to OS's with a bootable pendrive, like Windows PE or Ubuntu Live, which I'm using to test whenever the wifi, RAM, etc are working and being correctly recognized.

    I have a 2.5" SSD, but it only contains personal data, just like the second M.2. Already tried removing it, booting with and without it, reseting BIOS with and without it, doesn't really changes anything.

    I don't remember seeing option to choose AHCI, but I do remember seeing VMD (or something like that), when pressing ctrl + s at the "Main" section on BIOS, tried enabling and disabling it, also didn't work.
