Can I run SDBI_CLUSTER_CHECK without option "Find duplicates"? Is there any impact?
Yes, it is possible to run the report without any impact. The option "find duplicates" is also called "sort check". The cluster interface relies on the logic records being sorted properly by the rest key, which is checked when the option "find duplicates" is enabled.
How can I know more about the runtime of SDBI_CLUSTER_CHECK?
SAP Note 1309728 describes the runtime.
Is there an alternative/faster option to check the cluster tables other than SDBI_CLUSTER_CHECK?

Can I run the SDBI_CLUSTER_CHECK job months in advance?
Yes, you can run the SDBI_CLUSTER_CHECK in advance. The reason to run in advance is to have enough time to fix issues, if necessary.

My quality/development system is a copy from production system, can I skip the SDBI_CLUSTER_CHECK?
