@Loic78570 the serial number can be customized by using DCU on te binary before flashing the device: https://github.com/Dasharo/dcu?tab=readme-ov-file#standalone
By default there is a generic serial number fixed in the firmware build. It doesn't work like that as you expect it.
Not sure if @wessel-novacustom does that for each laptop before shipping.

- @miczyg1 We do not yet since we are waiting for serial number integration support for the RTE flash device.
Is there a way we can change manually the value of that generic serial number, for use with tools such as Google Endpoint Verification Helper ?
@Loic78570 would you mind explaining your use case more extensively? Is Google Endpoint Verification Helper an open-source project? I tried to look for it but barely understood how it is used.
It seems that there are also other tools such us: https://developers.cloudflare.com/cloudflare-one/connections/connect-devices/warp/ Using dmidecode for serial number: https://developers.cloudflare.com/cloudflare-one/identity/devices/warp-client-checks/corp-device/#linux
@Loic78570 You could use DCU tool to set the serial number yourself: https://github.com/Dasharo/dcu
Although I think it's not in the initial firmware release yet @mkopec ?

correct, that feature was merged quite recently
We use a script that fetches the system serial number to make a correspondance between Google Workspace's device list and our EDR. To push our S/N on the EDR, we have to execute a shell command on the machine, as such, we execute $(sudo dmidecode -s system-serial-number) to get it.
We have recently bought three NovaCustom V54 14th Gen, are we able to do it ?
I managed to make a bootable USB key with the Dasharo Tools Suite on it, is it possible to change the serial number with it registered within the system ?

Unfortunately not yet, as @mkopec said, this feature has been added recently and is not part of the official release yet.
Tested on V540TU, Dasharo 1.0.0-rc5, Dasharo Tools Suite 2.6.0;
setting serial number in Dasharo image with dcu smbios -s XXXXXX command works.
