When you do "Security Bypass" procedure, your phone receives a pre-modified EROM that enables DreamBox features(unlock/repair/fullflash,etc).
If you flash MAIN/RAW_FS with DreamBox or any other "normal" software, it will not touch on "DreamBox Modded EROM" installed in your phone and you can always use Security Bypass boot mode.
You will lost the Security Bypass boot mode only with you update/repair EROM with non-tp solutions by others softwares, because it writes another patched EROM non compatible with DreamBox functionalities.
Then, if you not use non-tp recover solutions you will always get a DreamBox "Security Bypass" compatible phone!
