Coolant shut off valve exists or not exists?

[pgls651]

Wondering if anyone has knowledge of location of coolant shutoff somewhere in a Pete 579, 2017? Id prefer not to drain the whole system to get at a small DEF hose, and clamps have not been quite up to the job in the past. The last truck I had was Volvo vol and had this arctic shutoff thing, was a breeze to close off.
