Passing -D options with b2 to ASIO when compiling with mingw64 ucrt64?

Hi,

I try to compile Boost with MingW64 with ucrt64. I get warnings saying
I should define  _WIN32_WINNT with 0x0601 or higher and an error saying
I must define USE_W32_SOCKETS.

Is it possible to pass these on a command line to b2 or otherwise,
without interfering with Boost's source?

TIA
