I don't think so, borg shields had adaptive functions which worked against weapons based more on clever manipulation of energy than on the volume of energy. Death Star was just emitting enough of the shit to completely smash Earth-size planet not even into pieces but into dust (planetary scale dust that is) in split second. Star Trek pretend to not entirely ignore physics so that would be most likely way more then enough to destroy any vessel of borg, adaptation or not.

Some adaptation is always possible. They might have to develop/assimilate that portal gun from Picard S03 in order to redirect the beam away from them. It's reasonable that simply adapting their standard shields wouldn't work.
