Yes, I do have that enabled. I have to clarify my statement: I do not mean it never uses the HOV, but that it rarely using it, prefers to leave when I would have stayed in the HOV.
To further elaborate on my problems (including the use of HOV lane), I have documented my problems with NoA on my trip this morning using tesla dashcam clips:
1. The first clip shows that I am traveling on the left-most main lane of the busy 3-lane highway, when the HOV lane becomes available on the left. NoA makes an attempt to switch (about 30s in the clip), but it is too slow, does not accelerate, a car comes up (HOV lane moving significantly faster) so it cancels attempt, I see it gives up on lane change so I take over (at about 37s) and make the change manually on the next opportunity.

2. A couple of minutes later a highway interchange is coming up for which I need to leave the HOV lane. NoA indicates that it wants to switch, but shows red line as another car travels parallel to me in the next lane. There is space both in front and behind the car, so NoA would need to either accelerate or decelerate a bit to be able to make the switch, but it fails, keeps driving side-by-side. When the dashed section between HOV and main lanes is about to end, I take over and quickly make the switch manually. NoA would have stayed in HOV and miss the opportunity for the upcoming highway interchange.

3. Next mistake is still visible on the same clip above (at around 20 seconds in). I have turned back on NoA and now traveling in leftmost lane of the 3, but for the highway interchange I need to be at least in the middle lane (which splits), I am watching NoA and see no indication that it would plan to make the switch, so I take over and switch manually. This mistake would have sent me further down on the wrong highway, causing a significant detour to get back to my destination.
4. The fourth mistake of NoA is still on the above clip (at around 39 seconds in). After the highway split, a new HOV lane starts on the left, but NoA makes no indication that it would make the switch for it, it wants to stay on the busy main lane, while the HOV lane is sparse, so I take over and manually change to HOV.
5. The next time there is a dashed line between the HOV and the main lanes, NoA indicates that it wants to switch to the main lanes leaving the empty HOV for the busy main lanes as shown in the
clip here. I have manually cancelled this lane change to stay on the HOV.
6. At the next opportunity, NoA again wants to leave the HOV lane, this time the main lanes are not so busy (but the HOV is completely empty) as shown
in this clip, but this time I have allowed NoA to make the change (at about 50s in the video) even though I could have traveled another 10km in the HOV before needing to leave for my destination.
7. Further down the main lanes got busier again, while the HOV was clean (which is why I would have preferred to stay in HOV, I know this traffic pattern from experience). The
next clip shows how NoA decides to switch into the busier and slower middle lane from the empty left lane at around 38 seconds into the clip. This is still about 6 km before my exit, so unnecessarily early to make the move to the right.
So that is 7 bad decisions of the NoA within the time frame of roughly half an hour. None of them was safety concern, but two of them (#2 and #3) would have cause me to stay on the wrong highway and miss my interchange.
