No basis for a DVTRO, since it sounds like there's no recent facts which demonstrate any immediate risk. Until you get into court and modify the custody order, your ex can allow the kids to spend time with anyone she wants during HER custodial time. If she's depriving you of YOUR custodial time, that's a different issue.
It is not clear if your ex is sending the children to your father during her time, or during your time. How do your children feel about the visits" Do they feel uncomfortable. If you were in Santa Clara County, I would suggest that you as for a hearing and what we call a "screening" at FCS as the question is the best interest of the children and if you think that there is an immediate danger, then someone would investigate and report their findings to the court.
Keep a diary. That is very important.
No basis for a DV order, but grandparents don't have automatic visitation rights . You could ask for right of first refusal so that the other parent should must allow you visitation whenever the children are left with a third party for more than 4 hours. You can also seek to deny the grandfather visitation.
