I would look at doing Cyber Essentials (NCSC course) or CompTIA A+ (basic overview into ICT).
If that's out of your budget, or you don't like exams, then maybe the hands-on experience would be best.
If it helps, I did a BSc (Hons) in ICT, which helped me get into the field of cyber security, although it was a tough road.
Most companies ask for a few year's of experience, but fail to provide the training needed to upskill.
Have a look at cyber security courses (free) on UDemy or Coursera, spruce up your LinkedIn page, connect with cyber security folk for their advice, and look at their jobs (what they are working on + what they worked on in the past) to get an idea of what you need to do to be at their level of expertise.
Hope this helps.
