Reading some of the statements it seems possible that arriving into 2E would give access. I haven't tried it so if you have better knowledge such as an arrival into 2E with a transfer that stopped you from having access I will defer to you but on some pages it agree with you and others it's more vague.

So if you cannot change your ticket to the earlier flight, the EY lounge, as a paid access, should be your best option.
