Looks good

if/how is it related to: https://github.com/Dasharo/osfv-scripts/pull/83/files ?

well it is related - I guess the same effect can be achieved by just using --skip-snipeit.
For example, in the original issue:

It would be useful to be able to use this script also ad-hoc, using any RTE, not only for devices in lab.

Currently it looks like this:

osfv_cli rte --rte_ip 192.168.4.64 --model 'MinnowBoard Turbot B41' flash probe  
No asset found with RTE IP: 192.168.4.64
DUT model retrieved from cmdline, skipping Snipe-IT query
Using rte command is invasive action, checking first if the device is not used...
Error checking out asset None
Response data: None
Exiting to avoid conflict. Check who is working on this device and contact them first.

we could just use --skip-snipeit to achieve what we want.
Is an ad-hoc-mode even needed?
