Are there any guidelines on the use of modules inside boost?

No.

Are we planning any steps for adoption of them?

That question is answered on a library by library basis. Speaking for Boost.Beast, modules requires C++20 while Beast only requires C++11, so Beast will not be "using modules" any time soon.

I'd rather treat C++20 modules in 2020 as C++11 rvalues in 2011. If the compiler supports them then Boost library authors may use them in the library and provide benefits to the end users. But they won't become a required feature in next 20 years. I'd expect some kind of guidelines and macro in Boost.Config as soon as we get some compiler that properly implements the C++20 modules. Right now there's no such compiler.
