The idea for this branch comes from #212.
I think checking the account status at the end of the function is redundant, so I commented it out. Do you mean to explain the reason when submitting the PR?

    // check!(
    //     !marginf_account.get_flag(DISABLED_FLAG),
    //     MarginfiError::AccountDisabled
    // );
