Is a son considered disobedient to his father if he wishes to be independent in his work, while the father controls the son's work and prevents him from becoming independent, knowing that the father expelled him from the pharmacy that the son owns?

Filial piety is among the greatest deeds, and Allah has associated it with His worship. You must be patient, observe your father's rights, and treat him kindly. Righteousness towards him is a gate to Paradise. It is forbidden to abandon a parent or harm him, even by uttering a sigh of displeasure. There is no blame upon you for working independently, especially if working with him leads to corruption. So, seek another job while maintaining your filial piety and kindness towards your father.
