No Bitlocker

So i used image assist to create our windows 10 image for our new hardware - 5420. The process went smoothly and was quite  easy. However, when viewing the online first article i see that the drive is bitlocker encrypted. I open bitlocker and confirm that it's not active. Research shows that windows will automatically encrypt drives on a system with TPM, UEFI and secure boot enabled. I don't want these drives encrypted. We do plan on implementing a solution in the near future - possible dell encryption, but we are not yet ready. I am worried that the bitlocker encrypted drive will cause issues with either reimaging or implementing encryption. I am sure i am not the only one. Is there something that I should be doing during the image assist process to prevent this?
