Sadly no as stated there:
https://devices.ubuntu-touch.io/device/s3ve3g/

Note: There are 2 variants of S3 Neo, GT-I9300I and GT-I9301I, called also S3 Neo+. Obviously only the latter one is compatible with this port. We are working on determining if we can support Gt-I9300I as well.

But you can try and contact the porter and work with them to try and support your device as well.
