restrictions allow. For updates to the status of VACs in your country,
contact:

resuming, existing customers will be contacted.
Some English Testing Centres are also resuming services. Visit the
International English Language Testing System (IELTS)’s

your Secure English Language Test.
Getting your documents
Due to worldwide border, travel and public health restrictions it may not be
possible to return your passport at this time. Contact the VAC where you
logged your application to see if courier return is available in your
location.
British nationals abroad who need to apply for a passport
If your country’s VAC is still closed, you won’t be able to apply for a
British passport. You can find your nearest visa application centre and check
if it’s open. We will
prioritise customers who have been waiting for a decision before accepting new
applications.
If you urgently need to travel to the UK, you can apply for an emergency
travel document.
If you are applying for a Global Talent, Start-up or Innovator visa
If your endorsement from an endorsing body has expired because you have not
been able to travel to the UK you may still be eligible for a visa. You should
make your application as planned and we will consider all applications on a
case by case basis.
If your 30 day visa to work, study or join family has expired
If your 30 day visa to travel to the UK for work, study or to join family has
expired, or is about to expire, you can request a replacement visa with
revised validity dates free of charge until the end of this year.
To make a request, contact the Coronavirus Immigration Help Centre. You’ll
need to include your name, nationality, date of birth and your GWF reference
number with ‘REPLACEMENT 30 DAY VISA’ in the subject line. If you’ve already
contacted us about this, please let us know in your email.
You’ll be contacted when our VACs reopen to arrange for a replacement visa to
be endorsed in your passport.
You will not be penalised for being unable collect your BRP while coronavirus
measures are in place.
This process will be in place until the end of 2020.

Reviewer feedback on this answer:
This answers the question directly, this give an outline of what to do and it gives a list of what types of document they need to apply for a passport.
This directly talks about how people outside of the country who need passports can get their documents, and who to contact.
This seems like a good answer.  It says that a passport might not be available.  It gives a lot of relevant information.
