This is exactly how I’m charging our lithiums. Our built in charger doesn’t have a true Lithium profile, you just manually enter the parameters you need. I intentionally left my top voltage a few points low so the solar panels could do the rest. You’d much rather undercharge your lithium’s than over charge them.
I don’t have BB batteries but the guys there still answered this question when I asked them. The only issue with undercharging lithium is you’ll have slightly less power. If your solar makes up the difference then, even better.
I also installed the Victron BMV-712 battery monitor for insurance in case my chargers built in monitor wasn’t accurate. It had a true lithium profile in the software.
