Help with charging

Hi
I am currently on Octopus intelligent. When I go away on holiday, I stop the battery charging on Intelligent tariff. However it reverts back to the charging after one day. How do I do this for a couple of weeks so that my battery is only charged by my solar panels
Thank you
GivEnergy battery 10.5 with 3 kW AC charger

Balou put in on solar only on the app

Thank you

I have the target SoC for the overnight charge window set quite low so charging does not kick in unless it needs to.
