The only concern is the terms of the EULA so that's why the earlier poster says "for casual development"
There are a lot of guides online, including "one command" shell/powershell scripts that will automatically pull down the right files for you, and use the vmware/virtualbox api to create the vm automatically, and patch the bootloader to get Catalina or Big Sur loading, etc - if past experience is any indication, people probably already have Monterey beta loading fine already.
again, it's not a matter of "how" it's whether you (or Apple lawyers) care about the EULA.
