Is there a possibility or bios update to enable a limit on the battery charging on iWork 20 Pro?

Hello there, i am happy with my Aldocube iWork 20 Pro. With the help of a LCD Screen Heating Pad i sucsesfully managed to even open it (glued all the way around) and changed the SSD to a 1TB KingSpec M.2 SATA SSD, 1TB 2242 SATA III 6Gbps Internal M.2 SSD, Ultra Thin NGFF State Drive. Works fine. The only thing i miss is a possibiliy to extend the ram .. but i think its solderd on , Right?

And Ive got a big wish:

Í sadly dont find any possibility to limit the battery charging to say 80 percent to extend the battery lifetime.

Is there maybe going to be a bios update adding that feature or did i miss any settings?

´Greetings
