LGTM! I'll wait for @driazati to take a look

Code looks good to me, if it works I’m good with merging but #13335 does this along with some other cleanups. To test we’ll need to push the PR branch to apache/tvm to actually run the Jenkinsfile changes nvm this is already done!

@driazati I'm fine with using #13335 for this change since it has other changes too.

Can we close this since #13335 is merged?
