Yes. See datasheet section 5.2.4 MACRAW on page 108.
You can use MACRAW
simultaneously to the TCP/IP mode.
Can you disable the internal TCP/IP processing entirely, when the host
wants to use its own IP stack?
Having a chip with an embedded IP stack is useful for a lot of things; I
tried to convince the powers that be at my employer back in 1990 that we
should develop and sell such a chip. But when you're trying to emulate
a DEUNA, DEQNA, DELUA, or DELQA, it seems like it would only get in the
way, since those interfaces operate at the Ethernet frame level.
