CI: temporarily disable DRB integrity protection in B200 pipeline

Temporarily deactivate DRB integrity protection in SABOX-B200 E1 testcase
to avoid CI failure due to low measured throughput. Our investigation
suggests that the low throughput is likely due to limitation of the UE
(Quectel RM500Q), which appears to restrict the maximum data rate when
integrity protection is enabled. This limitation is not observed with
Quectel RM520N.
