Some certainly do allow you to apply without Geography while others strongly recommend/require it so it's probably a good idea to do some research into it.
Lots of Geography courses do not actually require you to have taken it at A level. Here are just a few examples and there are lots more -
Sussex - https://www.sussex.ac.uk/study/under...ch?q=geography (no specific subjects required)
Sheffield - https://www.sheffield.ac.uk/undergra...2/geography-ba (no specific subjects required)
Leicester - https://le.ac.uk/courses/geography-ba/2021 (no specific subjects required)
Aberystwyth - https://courses.aber.ac.uk/?study_le...text=geography (no specific subjects required)
