Either will work.  However, the idiomatic and fastest way to do it is:

PUSH-OMIT-CONTEXT
OMIT 30 Sep 2019
OMIT 28 Oct 2019

REM Mon +3 FROM 2 Sep 2019 UNTIL 2 Dec 2019 SKIP AT 12:00 DURATION 1:30 MSG test
%b %3
POP-OMIT-CONTEXT

The "SKIP" keyword tells Remind to skip a reminder if it falls on an
OMITted date.
