You can use HAL_UARTEx_ReceiveToIdle which will return when the line becomes idle or the specified number of characters are received.

Or the 8 bit mcu way, interrupt from each incoming byte, when 0 or /n termination char is detected, flag the message for task to process it, and continue receiving in another income buffer.
