PGDL for non-law finalist aiming for a vacation scheme this summer?

[ggbj]

Hi, I am an international Chemistry student applying for solicitor vacation schemes. Do I have to register intent in taking the PGDL as a finalist non-law student? From what I know, since it is no longer a prerequisite to do the PGDL before sitting SQE, I don't have to actually do it? If registering intent is advised anyway, could I just theoretically write a date and 'place not confirmed'?
