Will there be the android tv version 11 or newer for ROCK 4B?

I’m testing some application demo using google voice service built in android tv system.
But there seems to be some compatible issues due to old gatv spec supported in Pie(maybe 0.4e i suppose, the newest one 1.0 were released in 2020), which is the newest version of android tv for 4B.
Is there any hope to find a custom built img of android tv 11 or newer for 4B?
