From Loupedeck's homepage ...
Loupedeck+ is compatible with Adobe Lightroom Classic CC, Adobe Photoshop CC, Skylum Aurora HDR, and Adobe Premiere Pro CC. Additional editing software will be added later this year.
Given the absence of Vegas Pro being mentioned, therein lies the answer to your question re Loupedeck+ at this time.
Others on the forum will no doubt provide suggestions about other editing consoles that are compatible with Vegas Pro.
