Yes, and at least the PDP-8 and PDP-11 are read only.
The interesting question is if any could punch. Maybe the PDP-10 could,
but I haven't heard of any other DEC machines that could.

I don't know how common card readers were,
but I don't think any DEC
machines could punch cards.
Almost all DEC machines up through early VAX supported card punch
options. They just weren't very common other than on PDP-10.
PDP-8: CP08
PDP-10: CP10 (multiple variants) and CP20
PDP-11 and VAX: CP11
PDP-15: CP15
(also earlier 18-bit machines, and maybe PDP-5, but I don't have
definitive info on option numbers at hand)
