Victron 3 Output Battery Charger question!

My intention is to purchase this Victron Energy Blue Smart IP22 12-Volt 30 amp 120VAC, 3 Output Battery Charger, NEMA 5-15, Bluetooth. I assume that each output provides 10A max.
My battery bank is consisted of 3 x 280Ah Echo Worthy Lifepo4 batteries connected in series for 36V system.

Can I connect individual outputs from this charger to each individual (12V + -) battery in my bank for charging purposes or I have to separate them during charging?

No that’s not possible.
The charger only has one common negative for all outputs.

Thanks for the quick response, bit confused but I am not Victron expert. I am switching from FLA to LI and my old charger will not be smart enough for Lithium. Does Victron offers solution for 36V batt. banks built this way? Much appreciated.

36V is a uncommon setup.
Victron doesn’t have chargers for that.

Only some of the MPPT solar chargers can be set to 36V.

Thanks!
