First checked the hardware and found a newer version BIOS on the Acer website.
Downloaded that specific for Windows 11, but Windows 11 was running in S-mode (which is default).
This means that only applications from the Microsoft Store can be installed and executed.
What a mis-configuration on a new bought machine!
Had to install from that MS-Store 'the' app to disable S-mode, and there was mentioned: You can NOT enable this afterwards!
Microsoft, give me 1 reason why you have S-mode enabled on a new laptop, on which I can NOT update the BIOS?
Linux next to Windows 11:
That should not be a big problem, although BIOS-settings have to be changed to 'see' the bootable (EFI) USB drive.
-
F12 during boot - enabled
fast-boot - disabled

Debian Live 12.4 works fine, only WiFi is not detected, and the machine does not have a RJ45 ethernet connection (anymore...).
We had to use a USB WiFi dongle to get all working, we must see to get the Intel WiFi AX201 with its BT (54f0:0244) working.
Until now without success.
Debian 12 is installed as second OS, first used Debian Live to partition the Windows to a smaller one, so we have enough for Linux (50/50).
Only once I had the Wifi in Airplane mode working, but after ending Airplane mode the device was not working.
This after changing /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm to .bak
Next enabled BT by copying 4150 to 1050 or something (sfi and ddc files)
After this never got the WiFi in Airplane mode again.
Not after removing the new created BT files and rebooted.
Nor changing back the .bak to .pnvm file and rebooted and again made the file .bak.
Now we try to update the kernel, as there are newer firmware build in.
Using:https://leosaa.medium.com/build-the-lat ... b09ec6af88
The command used to install additional packages holds more then 1 double names in it and missing:
libelf.dev
bison
flex
rsync
libssl-dev
As the update of the kernel only runs into errors, decided to search further for latest iwlwifi drivers:
On page 6 of this thread:
https://forum.mxlinux.org/viewtopic.php ... d&start=50
I found:
wget https://git.kernel.org/pub/scm/linux/ke ... 211.tar.gz ; tar -xf linux-firmware-20231211.tar.gz ; cd linux-firmware-20231211 ; sudo cp -R * /lib/firmware/ ; sudo update-initramfs -uk all
On: https://wiki.debian.org/InstallingDebia ... 20A317-55P
We found the solution:
WiFi driver included in debian 12 netinst will not work. So you should get a network connection via USB (e.g. using mobile device tethering), or use a full or Live install support. Once the minimal Debian is installed, you can upgrade the kernel downloading the upgraded kernel from another device, then you can install it through apt-get install /media/my-user-name/my-usb-stick/linux-image-6.5.0-0.deb12.4-amd64.deb. Finally, restart your computer to load the new kernel (you can check the kernel version with uname -a). You can now properly connect to Wi-Fi and finish installing missing packages.
The WiFi works now!
