How to change the "weak spot" collision from character to character in Lyra?

[Toiro (Japacult)]

Hello.
When choosing B_Hero_ShooterMannequin as the pawn class in HeroData asset, then “weak spot” collision will occur in the game start.

Changing the character appearance in B_PickRandomCharacter, then how can I change the collision?
What file generates the collision?

I would be grateful for your advice.
Thank you very much.

Solved.

LyraPawnComponent_CharacterParts → UPhysicsAsset

I changed this asset by cpp file, then I could have modified the collision.
