2010 Honda Odyssey ex with j35a6. Passenger side engine mount, how do I remove this bolt under the PCM?

Subject says it all pretty much. Not sure how to get at this bolt under the PCM? The factory service manual doesn't even picture it. It doesn't mention anything about removing that side of the engine mount on the timing belt procedure, but you can't get the lower half of the engine mount out without removing this part with the rubber..

I did this job a couple years ago and I don't remember how I got it? I can't get a socket on the bolt in the recessed hole on the lower half of the engine mount without removing this, and it looks like the rubber side needs to be replaced anyways
