Unfortunately Apple doesn't work that way - when it releases a new beta build, the same build applies to all machines running a particular operating system. Today's macOS beta update release, according to the release notes, to news sources like 9to5Mac, etc. was build 23A5301h, up from 23A5301g. I'm running it on a 2021 Apple Silicon M1 MacBook pro with 64 GB RAM, 8 TB disk space, and the highest CPU and GPU core count available.
