Since PF3 version 3.10.0 (Released December 2020) you can obtain ACARS ATIS for any airport you are flying to regardless if they actually have ATIS or not
From the version history document:-
ADDED A new (user requested) feature. This provides ACARS ATIS
reports for ANY airport, regardless of whether they have an ATIS facility or
not. So no matter where you're destined you will be able to receive ATIS
reports to determine weather and landing runway information. This feature
is OFF by default and to activate it you will have to go to the Advanced
Tweaks section to turn it on. You'll find it to the bottom right in the AcarsX
section in the Option #1 screen. Please note this feature ONLY works when
requesting ACARS ATIS.
Does that help?
