Yes, but not on manned flights. (Researching this is made more complex
because there were quite a few different AGC designs; AGC3, AGC4, AGC4B, AGC5
and AGC6, in addition to Block I and Block II.)

Sources differ a bit: "Journey to the Moon" (Eldon Hall) says (pg. 107) that
Apollo 6 was "the last flight with Block I guidance system equipment" - but
it's not clear if that refers to the AFC. "Digital Apollo" (David Mindell)
says (pg. 175) that Apollo 5 was "the first Block II computer flight".

So somewhere around there. (Apollo 7 was the first manned flight, and the
first Block II spacecraft, per Mindell, pg. 176 - note that Block II
spacecraft apparently != Block II AGC - very confusing!)

Both excellent books, BTW - highly recommend them both.
