SWD and BOOT Pin lockout - STM32WL33

[CEagl.1]

Hello,

I am looking to add an STDC14 header to my design.
I am concerned that by putting such a connector on the board, this will allow 3rd parties to simply buy an STLINK and reprogram my device.

I am not familiar with STM32, so in the interest of speed, can anyone tell me if the SWD and BOOT pins can be disabled following an initial programming?

If not is there a method of protecting these pins from 3rd parties?

Thanks

See RM0511, section 9.3.6: Size register (SIZE), where you can disable SWD (bit 20).

Hope that helps?
