Hi @User1226,
since there is no device-specific /e/ OS for the SM-A530F, the only option is to install a /e/OS GSI ROM. The Galaxy A8 (2018) can first be upgraded to Stock Android 9.0 (Pie), One UI and thus becomes fully Project Treble capable. Then /e/ OS ‘Q’-GSI (Android 10) could be installed.
But for that, by your own admission, you will need third-party help - preferably at your location. Online help would be extremely costly and exhausting.
