Is there a study on how to change our DNA so we don’t have a production of inflowing mm cells in our new blood coming into our bodies?

It an interesting idea. Researchers have used CRISPR, a gene editing treatment, to cure sickle cell anemia in people after only one treatment. The only problem is cost. Each treatment costs between $2-3 million dollars. I can’t see insurance companies or Medicare paying for this treatment until the costs come way down.

Our DNA is designed to tell rest of body what to do
DNA, or deoxyribonucleic acid, carries the genetic instructions that determine an organism's development, growth, and function. It's essentially the blueprint for building and operating an organism, containing the information needed to produce proteins, the workhorses of the body.
Here's a more detailed look:
Genetic Information Storage:
DNA stores the genetic information that is passed down from one generation to the next.
Protein Synthesis:
DNA contains the instructions for making proteins, which are essential for various cellular processes.
Cellular Function:
DNA plays a crucial role in controlling cell growth, division, and other functions.
Organism Development:
DNA provides the instructions for an organism's development, from a single cell to a fully formed individual.

It just seems we are fighting a losing battle if all our new blood is coming in from a bad blueprint in our DNA designed to control all the rest of our bodily functions.

We are treating output when we should be treating original input.

Agree, if you can get in a study, the costs are minimal
