'sudo phala sgx-test' now results in 'driver not found' error

[infrachris]

'sudo phala sgx-test' used to work, however now it appears to uninstall then re-install the driver and then results in an error. I've found other users with the same issue.

Output below:

~# sudo phala sgx-test

I believe this can be resolved if sgx-test allows for specifying dcap or isgx similar to sudo phala install:
install install your phala node
install DCAP driver
install isgx driver

sudo phala install will uninstall and re-install SGX drivers similar to sudo phala sgx-test. On some systems, SGX will break from the re-install unless one specified "isgx" in the sudo phala install command. Similarly, sudo phala sgx-test needs to allow for specifying 'isgx'.
