Can STM32F303 be programmed in multi-drop?

We have a system that uses hundreds of modules. Each module has 4 STM32F303 MCU's. Within a single module we would like to have one programming interface. Is there a means to program 4 MCUs with one programming interface?

CAN Bus DATA IS NOT GETTING RECEIVE NOT BY POLLING NOR Rx NOTIFICATION INTERRUPT ITS STUCKs IN TO "HAL_CAN_GetRxMessage(&hcan1,CAN_RX_FIFO0,&Rx_Header,Rx_Data);" if this receive API we are using polling mode instead of interrupt one

As per CAN new API i have implemented as followed sequence:-MX_CAN1_Init();CAN_filterConfig(); if (HAL_CAN_Start(&hcan1) != HAL_OK) { Error_Handler(); } if (HAL_CAN_ActivateNotification(&hcan1, CAN_IT_RX_FIFO0_FULL |CAN_IT_TX_MAILBOX_EMPTY) != HAL_O...
