Hope you are doing well. In general, your schematic looks fine. Just some comments:
NMI pin: I saw that the NMI pin (pin 21 / PTB18) doesn't have a pull up resistor. This pin controls the Non Maskable Interrupt for the KW. You must be sure that this pin does not go low, so you don’t have problems with this interrupt.
Your DCDC is configured as Bypass mode, right? Just a confirmation. (AN for DCDC Power Management: AN5025)
Confirm with the XTAL manufacturer if something special should be added or not for both XTALs.
Same for LDO and FT232, check with the manufacturer if the configuration are correct for those devices.

You must be sure that this pin does not go low, so you don’t have problems with this interrupt. => This pin is control RF Switch by low and high. So, I designed not pull-up resistor. And, you mean change other pin, that pin(NMI) must high always, right?
Your DCDC is configured as Bypass mode, right? Just a confirmation. (AN for DCDC Power Management:AN5025) => Yes
Confirm with the XTAL manufacturer if something special should be added or not for both XTALs.=> I apply XTALs like this : 32MHz±10ppm & xtal 32.768±20ppm.
Same for LDO and FT232, check with the manufacturer if the configuration are correct for those devices. => I see. I'll check this parts.
The PTB18 by default is NMI functionality. You can check this on the DataSheet. The comment is you just need to be sure that on startup (before configuring the pin on your program), the signal will not trigger the NMI function.
