Split Year Treatment - start date in UK

Dear HMRC, I applied BNO Visa and will enter into UK this summer. My HK employer will terminate my employment in HK by 31 July 2024. Before that, I'll come to UK for the period between 1 Jun to 30 Jun for settlement preparation, then fly back to HK for work for the period between 1 July to 31 July. My payroll will cut off on 31 July. I will subject to HK income Tax till 31 July 2024. When I apply Split Year Treatment, the start date in UK in SA109, shall I in put 1 Aug 2024 ? Thanks
