It's been a while since I've used Logseq, but IIRC you can use yaml front matter. The very first block in the page is special and if you enter YAML there, the underlying markdown will have that yaml block without any bullet points. It renders just like the `foo:: bar` properties.

There was a limitation though that it didn't handle nested YAML. (Obsidian has the same problem I believe though I haven't tested recently)
