MacBook Air 2017 Lagging with sequoia

Monterey 12.7.6 was the last official supported version for this Mac. Ventura & Sonoma worked fine but it started to get messy after installing sequoia. I turned off auto-software download options and kept only Security Responses on but still the system forces the new OS downloaded after which the whole becomes laggy as hell.

Please tell me how can I fix this. I don’t want to factory reset the laptop again.
