Is there a way to support 3 chains on Orange Pi

I’ve got Orange Pi SBC and found fork of LED-matrix library at GitHub - mrfaptastic/opi-allwinner-h3-rgb-led-matrix: Controlling one chain of 64x64, 32x32, 16x32 or similar RGB LED displays using Orange Pi (Allwinner H3) GPIO which support only one chain. But original Henner Zeller’s library support 3 channel running on RPi. My question is what is limitation of Orange Pi with suggested PCB adapter (active, 3-chain)? Why only one chain is supported?
