Can covalent bonds in water break by pushing them on a solid?

How do water molecules behave in the presence of a static electric field?

If I apply an electric field on water molecules, would they apply pressure to a solid surface (let's say a noble metal), and if so, what would happen? Could the oxygen wedge in between the atomic gaps on the surface of the solid? If the pressure is large enough, could the covalent bonds break?

They get ordered. Google for double layer.

the H-O-H bonds are hydrogen bonds, not covalent, but that doesnt answer your question.

from the Gibbs Free Energy perspective, pressure can have effect like temperature does, so there might be a critical pressure associated with an energy of reaction. I.e. having the oxygen react with the solid surface. What you're asking is if pressure can induce an oxidation reaction.
Yes, Probably.

That's not true. In a single, separated water molecule O-H bond is a mostly covalent one (with - as it is always the case - some ionic character). In solution things get more complicated, as water molecules interact by hydrogen bonds and hydrogen atoms are moving between molecules, but it still doesn't make all O-H bonds hydrogen bonds.
