Well, depending on how literally we take game mechanics, plenty of Warframes can actually just tank a fair amount of that. Frost bubbles and Rhino armor have an absorption window for the first few seconds after activation where incoming damage is negated and instead adds to the power's mitigation potential. Many Warframe powers just straight-up negate upwards of 90% of pre-mitigation damage, and shield gating fully absorbs any strike that would deplete the last of a Warframe's shields, and triggers a brief invulnerability phase (~2.5 seconds at max, I think) for any Warframe with shields (really just... Nidus and Inaros without them, I think?). And if we're really leaning on game mechanics, melee blocking fully absorbs attacks that they work on, which it might not against full-on boulders.
