NI is recognised as a "contingent" part of the UK. (contingent because as a gerrymandered legacy colony imposed on the Irish people it is a disputed territory).

There certainly is an implied agreement that there will be never again be a hard border with customs controls. Both govts accept this and the UK parliament voted for the NI protocol because of this. Disputing this is simply absurd and pointless. Pointless because the days of unionist dictation to the rest of the population are over and they won't be coming back. Get over it.
