Are self assessment SA100 & SA109 required if i am non-tax resident through SRT ?

I have completed the SRT (statutory resident test) and i am confirmed as Non-UK tax resident for the current tax year (2024-2025). However, i do have further enquiries for which your guidance is highly appreciated: 1) Do i still need to file SA100 & SA109 if i don't have any income generated in the UK for 2024-2025? 2) Do i still need to file SA100 & SA109 if i only have foreign income generated from overseas for 2024-2025? 3) Is foreign income generated from overseas for 2024-2025, taxable if i remit it in to the UK? 4) Are my assets (e.g. money) taxable if i remit it in to the UK? Thank you!
