Can we first update to make it cxx17 compatible?

[vinx13]

we are still using c++17, the error is because c++20 is not enabled

[zxybazh]

Original PR #16717 has been updated to make it c++17 compatible and passed the CI. This issue is created to mark that c++20 features may cause windows CI to fail during conda build.
