Is there way to change histogram buckets for k6 browser for custom trend metrics

Team, Is there way to change histogram buckets for custom trend metrics in k6 browser. Using custome trend metric, but it looks default explicit bucket max value is 10s, all values more than 10s, falls to 10s bucket, which does not give true metric trend. Sending these custom metric using otel exporter.

const pageLoadTimings = new Trend('page_load_time', true); 

./k6 run --tag=test-id=ui-tests -o experimental-opentelemetry ./ui-tests.js

Yes, you can’t change histogram buckets in k6 custom trend metrics—they’re fixed. For finer granularity, use Counter/Gauge with tags or process the raw metrics after export via OTEL.
