Riven Armour & Embitter

Hi All, question about Riven Armour applied by High Velocity Rounds.
The second sentence in description is worded with "gain." Can I use Embitter support to convert the gained damage to Cold? I ask because the gain is not hover-able like other "gains" but I know poe2 is generally thoughtful of word choice. Thanks!


Description reads:

Riven Armour is a Debuff inflicted by Hits, which stores 5% of the Pre-mitigation Physical Hit damage of the Hit that inflicts it as its Magnitude.

The inflicter's subsequent Attack Hits against the target will gain additional unscaleable added Physical Damage equal to that magnitude.

Enemies with Riven Armour cannot get their Armour Broken further.
