Works for me?

  $ pnpm add -D typescript@6.0.2
   ERR_PNPM_NO_MATURE_MATCHING_VERSION  No matching version found for typescript@6.0.2 published by Wed Mar 18 2026..

You could also set the config this way:

  pnpm config set minimumReleaseAge 10080 --global

You may be thinking about the project-specific config, which uses YAML.
