Field Level Security

Enforce or bypass FLS.

USER_MODE is a default option. You can set SYSTEM_MODE for all queries by adding .systemMode() to selector class.

public inherited sharing class AccountSelector implements SOQL.Selector {

    public static SOQL query() {
        return SOQL.of(Account.SObjectType)
            .with(Account.Id, Account.Name)
            .systemMode(); //default FLS mode
    }
}

public with sharing class MyController {

    public static List<Account> getAccountInSystemMode() {
        return AccountSelector.query()
            .userMode() //override selector FLS mode
            .toList();
    }
}
