So the rules say that benefits from crits aren't doubled...which would suggest the answer is no.
But the game seems to treat damage increases differently, like the increased die size from Fatal doesn't shut down double damage for the whole strike (Fatal would be really atrocious if it did) and in this case Unfailing is clearly just modifying the base damage, not adding an extra source like Deadly or the other benefit of Fatal.
So you could try to argue yes on that basis, though I think no is the answer you're more likely to come across (no is also the Foundry automation answer, fwiw).

Yes you don't double "Benefits you gain specifically from a critical hit" so the 1d4 isn't included because it is a benefit from critical hit:
Sometimes you'll need to halve or double an amount of damage, such as when the outcome of your Strike is a critical hit or when you succeed at a basic Reflex save against a spell. When this happens, you roll the damage normally, adding all the normal modifiers, bonuses, and penalties. Then you double or halve the amount as appropriate. As normal, round down if you halve the damage (though 1 damage halved remains at a minimum of 1 damage).
When doubling, the GM might allow you to roll the dice twice and double the modifiers, bonuses, and penalties instead of doubling the entire result, but this usually works best for single-target attacks or spells at low levels when you have a small number of damage dice to roll. Benefits you gain specifically from a critical hit, like the extra damage die from the fatal weapon trait, aren't doubled.
But at same time these benefits ignores critical immunities:
Immunity to critical hits works a little differently. When a creature immune to critical hits is critically hit by a Strike or other attack that deals damage, it takes normal damage instead of double damage. This does not make it immune to any other critical success effects of the actions, such as a critical specialization effect or the extra damage of the deadly trait. However, in some cases the GM might determine the added effects don’t apply.
