Does Section 654, subd. 654 of the California Code of Civil Procedure apply to punish for a single act of gross negligence?

"An act or omission that is punishable in different ways by different provisions of law shall be punished under the provision that provides for the longest potential term of imprisonment, but in no case shall the act or omission be punished under more than one provision." ( 654, subd. (a); see People v. Newman (2015) 238 Cal.App.4th 103, 111-112 ["[Section 654] generally precludes multiple punishments for a single physical act that violates different provisions of law . . . ."].)
