I have a situation where an area I would like to cover with the Rocket M2 w/120 degree sector antenna is only 2 miles or less away from the antenna. Can I effectively cover this at about 10 degrees out side of the 120 degree spread advertised for this antenna?
I would just try it, but it is a tower climb.

You'll see an additional 10 degrees off center only costs you 2-3 dB.

Yeah - you can find the theoretical gain of the antenna and then work the link budget with your other antenna. You can actually get a fair amount of signal straight off the *back* of a sector antenna - that is why someone makes a shield kit for it, I suppose.
If your receive antenna is also off-pointed, there is the possibility that a reflected signal may be a strong as the direct signal and that will cause problems. But if your other antenna is pointed directly at the sector, then the only debit is that the H and V polarities will be unbalanced - because they fall off at different rates as you go 'around the bend'. I expect the consequence of that will be to limit the MCS and bit rate below what it might be, if the two signals were more equal.
