Law, naval orders, and Channel enforcement

Could the Royal Navy be ordered to break domestic or international law during Channel enforcement?

Unlawful orders would be refused, and the government is expected to preserve treaty compliance because domestic politics and international precedent both matter.

This is explicitly a political assessment rather than a formal legal ruling. The government is expected to work within the law then in force, and naval personnel would refuse an unlawful order. A later follow-up expects treaty-compliant treatment of people rescued or intercepted at sea. Compliance also protects standards Britain may later invoke against states such as China.
