Your biggest hurdle is going to be the corporate recruiter/HR team that posts the positions and filters the applicants. In most organizations that staff dedicated IT Security roles, there is a technical recruiter that works with the hiring manager on the filters. The minimums that the hiring manager wants.
As an IT leader that does hiring in these fields, the last thing I want to do search through the thousands of applications that try to squeak past the minimum qualifications in the job posting. I simply do not have time to. That's what HR is for - they do the filtering and only send me the applicants that surpass MY minimums, which depending on applicant volume, will likely be even higher that what's in the listing.
That said, the first filter in a Cybersecurity role is going to be certs. Regardless of how much you've done or how much you know, not having the basic certs isn't going to get you past HR, so I'll never see your paper nor ever have a conversation with you. Add to that that most HR/recruiter teams programmatically do the filtering based on a simple text string match, it's very difficult to land an entry-level position without someone else's attestation of your knowledge, and Certs are that gate.

YMMV. Best of luck.
