Polarity of Data Enable (DE) signal from DCU

Is there a way to configure the polarity of DE signal for external displays?

In the DCU documentation I found the DCUx_SYNPOL register (55.5.10 in my version of the reference manual) that contains bits to swap polarity of HSYNC, VSYNC, CLK and even data bits, but no way to change the polarity of DE output signal.

There is the INV_PDI_DE bit, but can be used only for input signal.

Is there a way to configure the bahaviour of DE or we should assume that it can only be active high?
