Failing to set url for the boot entry and very sad about it

[xnox]

my Dell laptop firmware autogenerates PciRoot/Pci/USB/MAC/(...,0)/.... based entries whenever usb network hub is plugged in. However, they are doing dhcp without any URL and in my office i don't control DHCP to set the URL to a realistic location.

In my dell firmware by hand, it doesn't let me "browse" the usb nic path to manually provide a url =( (more sad).

And when I use efibootmgr to add an entry it only generates MAC(...,1) based entry which upon boot claims that no such path is found.

Has anyone been able to use efibootmgr to specify usb nic bootentry with a custom url?

Should i try to make all of that work?

Is my firmware broken? or are there reasonable improvements that could be made in efibootmgr?

I sort of wish i could "just" edit existing menu entry or copy it with extra/new url param. Cause my firmware generated the usb-nic entry so i want that path exactly with added url.
