My Acer computer says no bootable device found https://www.diskpart.com/articles/no-boot-device-acer-7201.html#:~:text=%20How%20do%20you%20fix%20no%20bootable%20device,boot%20device.%20If%20you%20insert%20an...%20More

Called customer service at Acer: there fix was put it back to factory. Did that keeping my files worked again for five hours, the time it me to re-do my files again, did it again.
"Put it back to factory!!" Said to me again, Again.
 No not this time \
This fix is good for them because it is not using their time, it is using our time.
  Well in the case of a new Acer , Truly is their problem to fix it!!

A new computer should be a fun thing!

Better write a complain to Acer as we here are users like you.
To the point - UEFI/EFI is immature! Example - every *.efi boot manager is capable to change settings in BIOS. Second example - grub and efi shell are able to change even hidden settings in the BIOS by modifying variables... So the main issue is that OS has too much  direct access to the BIOS!
