How to skip crossref and semantic?

[sekaiyon]

By default SEMANTIC_SCHOLAR_API_KEY, CROSSREF_MAILTO and CROSSREF_API_KEY are turned on and I want to do everything offline - some of the papers and sources I use are not indexed there and I don't want to meddle with setting up the API keys (I am a noob actually). How can I turn off the check for these variables and everything they entail?

I'm getting stuff like this:

SEMANTIC_SCHOLAR_API_KEY environment variable not set. Semantic Scholar API rate limits may apply. CROSSREF_MAILTO environment variable not set. Crossref API rate limits may apply. CROSSREF_API_KEY environment variable not set. Crossref API rate limits may apply.
