You are fine, just don't let it sit at low SoC. The "battery damage" comes from the fact that Tesla's BMS on the 3/Y are somewhat parasitic, and continue to suck power from a discharged pack. There is added degradation from time spent at low SoC, but not "damage".
You do not need to do a balance charge often. I'd say 3 to 4 times a year is sufficient, just do not let it sit at 100% after this charge. Plan to drive it soon after it finishes. LFP is less susceptible to this kind of degradation, but it still happens.
