IIRC Clover can extract at boot up, see Clover section for any info. When actually in Single User mode, what can be done is limited because the frameworks haven't loaded, so even a majority of command line tools will not work, just vary basic ones.

Theoretically this should do it:

ioreg -lr -c'AppleACPIPlatformExpert' -d1 | grep 'ACPI Tables' | sed -e 's/.*DSDT"=<//' -e 's/>.*//' | xxd -r -p > '/Users/name/DSDT.aml'

 

What the command does, is showing the 'ACPI Tables' ioreg property, cutting down the line to the bare hexadecimal content of the DSDT and converting it into binary form to the given path.

Replace "name" with your user account name or chose a completely different path, as you like.
