how to change animator bool of other player

Options
When this unit dies I want to stop other player's unit attack animation. how can I make this happen?
private void OnTriggerEnter(Collider other)
    {
        if (other.tag == "Player"||other.tag=="PlayerM")
        {
     
            other.gameObject.GetComponent<PhotonView>().RPC("Combat1",RpcTarget.Others,dmg);
        }
       
    }
   

    [PunRPC]
    public void Combat1(float dmg)
    {
        health -= dmg+(stats.strength*0.3f);
        if (health <= 0)
        {

            isDeath = true;
            animator.SetBool("Death",true);

            photon.RPC("WinnerStop", RpcTarget.All,false);
        }
    }

    [PunRPC]
    public void WinnerStop(bool holder)
    {
        animator.SetBool("Attack", holder);
    }
