Research direction
Open OCXO_DaughterCard_AbraconAOCJYR.xlsx and compare its R6 entry with the attached schematic. Mark R6 as DNP for the Abracon AOCJYR option, then review the other BOM files for components belonging only to alternate oscillator options. Done means the Abracon BOM avoids the physical interference and any additional removals are documented.

Description
While manufacturing the OCXO Daughter Card it was found that resistor R6 interferes physically with the placement of the Abracon AOCJYR OCXO (Y3).
R6 should be marked as DNP (Do Not Populate) in the BOM to avoid this issue when using the Abracon AOCJYR OCXO. In the schematic, R6 appears to be used by the SiTime SiT7511 (Y2) but not by the Abracon AOCJYR (Y3).
The BOM also includes components used by the other OCXO options, It's unclear if this was intentional or an oversite. It may be useful to review the rest of the BOM files to remove components that are not needed for the specific oscillator being used.
