Yup, the government absolutely can "advise" the monarch to do whatever they want as we saw in that other sub-thread. If the monarch refuses such "advice" they can be replaced, I doubt Parliament would go to all the extraordinary bother to execute a modern King, especially over such small beans - but if the King won't go they can either abolish the monarchy (it wouldn't even be that unpopular to do so right now) or just replace them anyway, passing a law which says actually no, that's not the King, this other person is monarch now.
Most recently Assent was withheld from a law passed in Scotland, on the advice of the British government. This conflict makes sense, the Scottish Parliament is necessarily subsidiary, and this was basically a Culture War law, in my opinion the Scottish were on the right side of history, but it's not astonishing that (as conceived when the Scottish Parliament was set up) the British parliament could say "No".
Before that the last time assent (as opposed to consent) was refused in 1708 is genuinely interesting. It was used because of unfortunate timing. Parliament said OK, those Scots seem useful, we don't fully trust them but we need more armed men and nobody doubts they can fight, so here's a law arming the Scottish. And then, with the Bill passed but Assent not yet granted, they received news of a French Fleet landing in Scotland. Suddenly giving arms to the Scottish seemed less clever as who knows if they'd be on France's side. So Mary was told (by the Government) to withhold Assent from that bill.
