Stm32 blackpill usb bootloader upload issue

Hi !
I just upgraded to a new stm32f401 black_pill board. Previously i had stm32f103 blue_pill board to which i uploaded usb_bootlader using STM32cubeprogrammer over UART (using FTDI module).
I've been trying for a while but unlike my previous experience with blue_pill, uploading usb bootloader to black_pill is'nt that simple. Whenever i connect the black_pill over UART, it breaks connection saying: "STM32 read protection is enabled, disable RDP to continue"

I do not have any ST-LINK device (nor available at any approachable seller) to do it that way.
Is there any way to do it using FTDI or atleast disable the Read Protection on the board ?

Thanks,
