[STM32L451] Is hardware enabled IWDG started when System Memory (factory bootloader) is booted

I have a system in which I have enabled IWDG in hardware (option bits).

Now I would like to use preinstalled STM's bootloader to update the device, but I'm not sure if the IWDG will be started.

In case the IWDG is started when Factory bootloader is booted, is there a way to get back to Main Flash area? IWDG period after reset is 0.5s, which not long enough for the programming...

Thanks!
