My understanding is that GoPro CineForm is an open source video code, not a video OFX plugin. Video codecs are built in to Vegas Pro as part of its program and aren't able to be user-installed as can be done with OFX and VST plugins. You can put in a feature request to the Vegas team asking that they look at whether CineForm can be added as a codec to Vegas Pro - https://www.vegascreativesoftware.info/us/forum/vegas-pro-feature-requests--134374/?page=24 - in a future version of Vegas Pro.
Otherwise, you might want to search online for another program where CineForm can be used and then export for use in Vegas Pro. An internet search came up with https://gopro-cineform-studio.en.lo4d.com/windows but I have no knowledge of it so can't attest to its use or effectiveness.
But the other question is: why do you need the Cineform codec? It was a great choice to transform footage like HEVC to a better footage for editing years ago. But today I would test if my systems can decode the footage directly. There have been significant improvements for HEVC, for example.

Is there a particular reason that you want to use Cineform for alpha rather than a standard Video for Windows template with the Video Format Field set to 'Uncompressed' and the alpha checkbox ticked (as it is in your pic upload)? The Apple ProRes render option also does alpha. But in both cases, the rendered files are large.

"...But in both cases, the rendered files are large." For this reason and for speed.
