Apologies for not responding to this sooner, I was away for a bit.
Here is a build based off 2025.30k experimental release with support for D455f model, as well as a few others: Dropbox
We are about to do an official release very soon, so these changes won’t be in that build, but the one after that.
And to answer your question above, if you wanted to manually add support you could use the CPlusPlus TOP workflow and manually create your own RealSense TOP using the RealSense C++ SDK. Note that, you would have to implement all of the RealSense camera integration from scratch.
