VLAN translation on originating switch?

Good morning all. Possible stupid question incoming, but I've never used VLAN translation (mapping) before.

So I've got a Nexus switch, with devices in VLANs 10 and 78 connecting to an Arista (which I don't control or have access to), which connects to the internet. The link btwn the Arista and my Nexus only allows VLAN 78 across it. Can I translate VLANs on my end from 10 to 78 as it goes through my switch?

Reading, it sounds like VLAN translation works on ingress at trunk ports, which leads me to think it wouldn't work if I set mapping on my Nexus trunk port? But maybe (hopefully) I'm reading incorrectly?
