TLS 2K packet limitation

I would like to know more about the TLS 2K packet limitation in the nRF Connect SDK.

Is there a way to not be constrained by this limitation. I've seen some posts about Zephyr Native TLS. It seems it is an option for the Serial LTE Modem (SLM) application.

Is it possible to enable this in a custom nRF9160 application? Are there any downsides in doing so? Would I still be able to use other nRF SDK Connect libraries/feature like the FOTA library and REST client? Or would that need to be rewritten or modified?
