UKVI has now also published further concession policy on GOV webpage in relation to students:

• The concession also makes a provision for Ukrainian nationals and their dependants to waive the requirement to provide documentary evidence. This concession applies when you are making a permission to stay application and are unable to provide the required documents. If you wish to rely on this concession, the guidance advises that you will need to provide a written explanation as to why you cannot provide the document that you would normally be required to submit to support your application.
• To be eligible under the documentary evidence concession, you must have lawfully entered the UK prior to 24 February 2022, or made an entry clearance application and arrived in the UK after this date.
