Sure, it's a similar process as requesting from IRCC. When you submit the request at
https://atip-aiprp.apps.gc.ca/atip/welcome.do?lang=en select CBSA instead of IRCC and follow the instruction there after. The consent form for CBSA is different from IRCC's and can be obtained from
https://www.cbsa-asfc.gc.ca/publications/forms-formulaires/bsf745-eng.html
IRCC and CBSA both use the same GCMS system platform and have access to the same information when it comes to the Gcms Notes. While the GCMS platform is the same the extent of redaction taken by IRCC and CBSA for the exact same information varies. There is more info on security in Gcms Notes from CBSA vs IRCC but CBSA on the other hand can/does redact more personal information.
One drawback of requesting from CBSA used to be that they would send the information via postal mail but during the pandemic they send it via email.
All the best.
