Need compiled firmware

I appreciate this community to get much information with developer’s honorable knowledge.
The reason I am writing this post is that I met the trouble.

I am using ubuntu18.04, which has sort of tup pkg problem, so that I cannot compile own firmware.

I really need this part of fixing to control SPI encoder, but in the firmware ver 0.5.4, these terms are not applied, I know.
Could you do me a favor to share some compiled firmware? If so, would be greatly appreciated.
Thank you.

Sure, contact me (Paul) on Discord and I can send over a build tomorrow EST
