@ehsandeep any updates about this issue?

[tarunKoyalwar]

implementation lgtm !

• rename disable-merge-path -> disable-path-automerge for better context (cc: @ehsandeep)
• add integration test for this case

Note:

Current Implementation only disables path automerge with new option and
automerge of query parameters will exist by default / remains unchanged
