Intel is part of IWC, which meets 2x year for DCO selection.
You may not be as competitive as your peers for Intel, however. Most applicants for intel have significant experience in intelligence, foreign policy, scientific/technical/cyber fields, or special operations. Some do get in without checking any of those boxes - but they typically are Ivy League lawyer types or politically connected. To put it in perspective for you, ENS Reince Priebus (1205 HR) was the Chief of Staff of the White House and didn't get picked up for DCO Intel.
I don't mean to make you feel bad by this next question, but what was your motivation for enlisting as a BM (which is a fine rate) two years ago if you are shortly soon afterward looking to switch to Supply or Intel? Why not enlist as an IS or LS, if those career fields appealed to you? I would guess that the DCO selection boards will want to see you put some more time into BM and advance to E5, maybe E6, while also continuing to progress in your civilian job and education/certificates.
Lastly, I always put this out there as an option because not a lot of people consider it: If your only goal is to be an officer, and if you happen to be a religious person, you can also consider Chaplain DCO (which may require getting an additional degree/credential to meet the PA requirements).
