IRC48M clock to output pin when voltage is lower than 2.7 V?

Hello guys.

Little help needed. I need high frequency output on my low power project. I'm using MKL03Z32VFK4 MCU. Is there way to output IRC48M to a pin when VDD voltage is lower than 2.7 V (I'm using CR2032 battery)

Datasheet says that:
Page 179: IRC48M clock (IRC48M clock can be output to PAD only when chip VDD is 2.7-3.6 V)


https://www.nxp.com/docs/en/reference-manual/KL03P24M48SF0RM.pdf

What happens if voltage is below 2.7 V? Usable voltage range of CR3032 is about from 3.4 V down to 2.4 V.
