Yes, gcc 10.1 has introduced support for the SVE2 intrinsics (ACLE).
Moreover, starting with the 8.1 version, gcc began to use SVE in certain cases when it succeeded to auto-vectorize loops (if the correct -march option had been used).
Nevertheless, many Linux distributions are still shipped with older gcc versions, so SVE/SVE2 does not work with the available compiler or cross-compiler.

You must upgrade gcc to 10.1 or a newer version.
