High frequency signal on a low frequency GPIO

High frequency signal on a low frequency GPIOhttps://devzone.nordicsemi.com/f/nordic-q-a/67531/high-frequency-signal-on-a-low-frequency-gpioHi, I am using P0.10 GPIO of nRF52840 (QFN package) as an output for driving a transmission circuit with an 8MHz digital signal. According to the datasheet this pin is defined as a low frequency I/O only which does not support high-drive mode.
