Can i access the firebase realtime database security rules via REST?

I'm looking to set up emulated testing of my security rules, and currently the docs recommend loading your rules into a file and then reading that file into the emulator.

const rules = fs.readFileSync("database.rules.json", "utf8");

What I'd rather do is load in the latest security rules from my project, so that I know that any changes I make to it can be tested instantly and are working properly.

Is it possible to access the security rules via REST?
