Is STM32L443 supported in Zephyr OS? If not, what is the timeline for adding this support? If I need to port myself are there any pitfalls with using the stm32l433xx Kconfig as a template?

Likely just going to need to merge in any extensions related to HASH or CRYP you want to utilize of the base functionality..
