maybe is possible if your phone supports USB OTG, there are OTG Y-cables, they provide power to the external device, you may try with eg termux (terminal app with linux commands) - there is 'udftools' on the packages, maybe your phone needs to be rooted (eg to use the udftools or even 'dd' on the external DVD/CD)
update:
had some time with 'termux' , /dev/ access is via root only , so rooted phone is a must (YMMV as eg some finance/banking apps refuse to run on rooted phones)
