Unless I missed it (please point me to the right page if i am wrong) comptuershare doesn’t provide individual CREST accounts, all share dealing outside physical share certificates are managed through the usual nominee process like most other brokers.
computershare for example hold your shares under Share Nominees Ltd (from what i read) under the exact same process that Freetrade use (Freetrade holding your shares under Freetrade Nominees Ltd.). You are the beneficial owner of the shares held by the nominee company on your behalf.
If you want to have direct name on the register ownership of the shares you will need to open an Individual CREST account at some expense. There are a few companies out there who will help you open on of these (for a cost of course), but i dont think computershare are one of them.
dont follow reddit conspiracies, you’ll lose all your money
edit: by DRS im guessing you mean Direct Registration System? and you’ve been following reddit hype about it? DRS looks to be a US/American scheme, computershare dont offer it in the UK. I suspect you’d need to open a US computershare account to take advantage of that, and of course lose out on ISA benefits. In which case your question about transfers doesn’t apply as you cant transfer an ISA to a foreign trading account.
