Thanks for having translated your request.
The options you have to be able to boot off an NVMe SSD with your old Acer Aspire Z3761 depend on the BIOS architecture (UEFI compatible or not) of its mainboard.
If the BIOS is an AMI UEFI one, you can modify it your own by simply following >this< Guide. If you mainboard BIOS is a Legacy (non-UEFI) one, you will have to use another method. You can find the related guides >here< and >here<.
If you are unsure, please upload/attach the BIOS file als *.ZIP or *.RAR archive.
Good luck!
