I've read the documentation regarding the new Bulk API 2.0 but I haven't found the way to send a request with the parameter concurrencyMode and set it to Serial instead of Parellel.

Can you help me ? Thanks.

Setting the concurrencyMode in V2 is not possible. I recently had the same issue and Salesforce support recommend using the V1 API to prevent the "row locking" issues we were having with V2.


Just found the idea "Bulk API v2 support for Serial ConcurrencyMode" https://success.salesforce.com/ideaView?id=0873A000000cRQWQA2
