In the federal system, the options for actually cutting time off your sentence are narrow. RDAP and substantial assistance to the government, which means cooperating with prosecutors and testifying against others, are the two primary mechanisms. Everything else, good behavior, programming, education courses, keeps you out of trouble and protects your release date but does not shorten the sentence itself.
If RDAP is not available at Aliceville's satellite camp, that is worth addressing before you report. If you have any documented history of substance abuse, you may be eligible to transfer to a women's camp that does offer the program. I took RDAP myself and received a full year off my sentence, plus six months of halfway house time on the back end. That is not a small thing. On a sentence of any meaningful length, that combination measurably changes your life.
The First Step Act, passed in 2018, did create an additional avenue through earned time credits. Participating in approved rehabilitative programming, things like vocational training, education, and other evidence-based courses, can generate credits that move your placement to a halfway house or home confinement earlier. It is not the same as cutting time off the sentence outright, but it accelerates your transition out of the facility. Ask your case manager specifically about First Step Act programming at Aliceville and which courses qualify.
If RDAP eligibility applies to your situation at all, pursue the transfer. The benefit is too significant to leave on the table because of facility assignment.
