Yes there is, although it's rare

Here is what I'd do if I were you:

Build a list of all the companies you could/want to work for

Build a list of all the linkedin profiles of their HR/recruiters/talents or (co)founders for small startups(you can use phantombuster or a custom puppeteer scraper)

Find all their emails using wiza, dropcontact or a similar tool

Use a mailbox warmer for a few days/weeks to prepare your mail address to send lots of mails without getting flagged as spam

BCC all of them asking if they'd be open to hiring part-time (or use lemlist)

you can also send automated linkedin invites/messages to them

Please don't do this. It's always obvious when you're receiving an automated email, and if someone is too naive to recognize an automated email, you probably don't want to work for them anyway.

HR being a bunch a tech illiterate boomers doesn't mean much about the rest of company

Automated cold email is done by 99% of companies and recruiters, it works if its done well

I was offered dozens of interviews that way, it works

Using a mailbox warmer is a sign something's broken with email.
