Question about streamlined filing

I have received conflicting advice from two CPAs about the foreign streamlined filing program and wondered if anyone here could help...

One CPA said that to use the streamlined filing service, you always have to file 3 years of returns and 6 years of FBARs, regardless of whether (for example) you're only late with 2 years of FBARs or two years of tax returns.
Second CPA said (based on my specific circumstances) I'm only eligible to file late tax returns through the streamlined program, and the late FBARs should just be filed separately with FinCen.

I guess my question is - has anyone used the streamlined service to file only returns and not FBARs?  Or to (e.g.) only file two years' worth of returns or FBARs, rather than the usual 3/6?

I used the streamlined offshore program to file 3 years of returns (20/21/22) but no FBARs as I was current with all FinCEN requirements having filed them each year from 2010 onwards. I explained in my streamlined Statement how that situation had arisen and it was accepted. Hope that helps.
