How esb PTX send multiple times when ACK is disable

I want to boardcast data using ESB to several PRX, how PTX can send multiple time let say 10 times under ACK is disable

Could you just wait for NRF_ESB_EVENT_TX_SUCCESS event on each packet and send the packet again 9 times more ?

I would suggest to add a packet counter in the payload. You increase the counter when you send a new packet.
