No, a 1 on the d20 for a death saving throw is still two failures
As you've pointed out, the death saving throw has a specific rule that says:
When you make a death saving throw and roll a 1 on the d20, it counts as two failures. (PHB, p. 197)
It specifically mentions the number on the die, not the total, which implies that even if you somehow managed to get a +19 through various buffs and such, it would still count as a 1.
This is similar to how critical failure on attack rolls work. From PHB, p. 194:
If the d20 roll for an attack is a 1, the attack misses regardless of any modifiers or the target's AC.
Now, you could argue that because the rules on death saving throws doesn't explicitly mention modifiers, that modifiers should therefore work. However, I believe that the important distinction is that both rules specifically call out a 1 on the d20 and states the result of that outcome, and that both are more specific that the general case where attacks rolls and saving throws make use of modifiers to get higher (or lower) results.
Hence, my conclusion is that the "roll a 1 on the d20" is the more specific case, and any sources of any modifiers cannot help you to avoid that. Rerolls, though, that's a different matter entirely (I'm looking at you, Halflings...)
