I have multiple Hisense Roku TVs can I change each broadcast name?

So I have 3 TVs in a small place. When attempting to connect an app from my phone to the TV I see: Hisense Roku TV Hisense Roku TV Hisense Roku TV MW's Firestick

Can I change those names to identify which room? I figured out which were which but changing the names would be easier.
