Agreed. It's not in the KB repository either (unlike 4.16.4.3, etc)
Also the sku is rather odd (RBR750-1STSQS). There's a couple of other variants nearby with odd extensions (-1RDQAS) and different firmware from the main branch.
I am wondering if they were built for a specific ISP? If so, the firmware might not be upgradable.

That’s an interesting hypothesis and to add additional context, I suspect the router and satellites I can’t upgrade were probably ones that came with my plan from Singtel (the Singapore phone company/ISP) while I also have an additional satellite I purchased separately. Maybe that’s the one I have that did allow a firmware upgrade. (Hard for me to know which was which after the fact.)
I gave up in the end as they became increasingly unstable and bought a new setup.
