there is a DB board fed from a centre tapped transformer only on single pole breakers. The board feeds instrumentation. Is there any issue changing it to 110v and tie the neutral to earth there is no socket outlets fed on this so can’t see it as an issue?

How can you tie the neutral to earth?
I must be missing something here, because the obvious answer is "with a bit of green and yellow stripy wire".
Make sure that the centre tap of the transformer is disconnected from the supply earth. Pick one leg of the transformer and call it "neutral". Connect it to the supply earth.
Whether or not it's a good idea to do that is another matter entirely.
