It doesn’t call it ACATS, it calls it “Outgoing transfer lock”. You can pick which vanguard accounts, too, if you have multiple account.

It also says a “Full Transfer Lock” is “Coming Soon”, that will apparently cover ACH transfers in/out, too.

I was able set a lock this morning!

I think it’s great if you can pick the individual accounts to lock. Last time I checked at Fidelity it looked like it was all locked or not. Does anyone know if you can lock individual accounts at Fidelity?
