You can't just send your resume blindly with that much experience.
First, you need to contact your connections in the companies you want to work for. And they will introduce you. With 17 years of experience, you know hundreds of people working in the industry.
If you don't know anybody in the company, then you need to find a recruiter that works there and contact them directly. Find them on LinkedIn and send them a message.
You can do the same with a hiring manager for that particular role. But that's harder to figure out who it is.
You just need to speak with people in the company directly. Sending your resume to some automated black hole system will not work.
However, to change a career, you need much less.
To get a very junior tech/programming job I would say it's something like 500-1000 hours.
That's about the same as most coding bootcamps. And a lot of people who went through a coding bootcamp were able to get a job in tech.
