Does Great Weapon Fighting allow the SRD version of a Vicious Weapon’s 2d6 bonus to be rerolled? [duplicate]

Does Great Weapon Fighting style allow Vicious weapons 2d6 bonus to be rerolled? Is it considered weapon damage? I know similar questions have been asked but need to know for this exact circumstance.

(Note: this question concerns the SRD version of a Vicious Weapon. The Vicious Weapon published in the Dungeon Master’s Guide adds a flat 7 damage, rather than 2d6)
