With for example Cisco, Arista and others one can configure multiple interfaces at once by doing:
interface ethernet 1/1-48
How do I do similar with VyOS?
As far as I know, VyOS is not support it. But you can set a bridge with multiple interfaces. then you can setup and configuration on the bridge.
VyOS is a router, not a switch OS.
Yeah and both Cisco and Arista and the others does routers aswell and do support using a range when one want to configure multiple interfaces at once.
Either “int 1/1-48” or in a list “int eth1,eth4-7,eth9”.
Ill file this as a feature request then.

Don’t compare VyOS CLI to Cisco CLI, they are two different worlds.
If you want to compare, compare it to PAN-OS, Juniper etc.
In VyOS (1.4) you can do for example:
[edit]
admin@vyos-rtr# for i in eth0 eth1; do show interface ethernet $i; done
Or set
[edit]
admin@vyos-rtr# for i in eth0 eth1; do set interface ethernet $i description test; done

Thats just awful and not intuitive but sure works as a workaround.
I prefer to compare to Arista which also have a linux backend and there it works to set a interface range or selected interfaces when in config mode.
Maybe you can try Ansible to set vyos interface with jinja2 template
I know there are probably a gazillion of overcomplicated workarounds to this problem.
I would still prefer be able to do this in config mode without some 3rd party extension.
The method @pepe described will work as a workaround until this shows up on its own in the config mode like set interface ethernet 1-4,7,9,12-24
Will file this as a feature request 
Is there really any useful use case?
I’m against this implementation.
The usecase is when one want to add or remove a specific configuration from multiple interfaces at once.
