How to change which bootstrapped stage0 rustc compiler is used when building rust?

Hi. Due to this issue

https://github.com/rust-lang/rust/issues/102897

I'm wondering how one can use a different stage0 rustc compiler than the default beta version? I need something that is <= 1.63.0. Thank you!

Somehow I found a website that shared how to find the bootstrapped compiler

wget https://static.rust-lang.org/dist/2022-08-11/rustc-1.63.0-x86_64-unknown-linux-gnu.tar.gz
