For what it's worth, it's devtoolset-11-gcc or gcc-toolset-11-gcc,
depending on the OS version.  The “11” is the GCC version, new versions
become available in the fall, about half a year after the upstream
release.  Old versions remain installable (even in parallel), but drop
out of official support fairly quickly (at least compared to our usual
support timelines).

Thanks,
