Can I switch my visa application from EDV to DTV after stating my intention at immigration?

Question regarding immigration statement and visa changes.

I recently came back into Bangkok via Suvarnabhumi and was told I have entered too frequently with a tourist visa. They gave me a form to fill a statement of my intention before letting me pass. In my statement I wrote my plans to obtain a EDV. The officer kindly told me this would be my last time i can enter with a tourist visa and suggested I look into DTV as it looks more suitable for me.

After looking into DTV I found I qualify for one of the DTV options and would also be able to follow through with my planned studies on the DTV too.

My question is can I apply for the DTV instead of the EDV now? Will my previous statement at the airport affect it since I put down EDV and not DTV? Due to new regulations I will be flying to my home country to apply. Just want to make sure I'm doing everything correctly to avoid pitfalls.

For context : Both my parents have worked and are currently retired in Thailand, my siblings also currently live and work in Bangkok hence my numerous visits in a single year to make an effort to see them often. I am happy to oblige to any rules and regulations but i wasn't aware of the capped entry and latest regulations.

Any helpful advice is most appreciated, Thanks!
