Code Review

This pull request removes a DBO test case to fix the CI pipeline. While this unblocks the CI, I have a high-severity concern about completely deleting the test. Instead, I recommend using @pytest.mark.skip to temporarily disable it. This approach preserves the test code, makes it clear that it's a temporary measure, and helps ensure it won't be forgotten. Please see my detailed comment.

skip it instead of removing?

there still exsits test_models_distributed_DeepSeekV3_dbo which is skiped below, I think it is duplicated to test on deepseek-v2-lite
