Set the max-metric in OSPF and OSPFv3 in IOS-XR devices:

RP/0/RSP0/CPU0:IOS-XR(config)#router ospf 65555
 max-metric router-lsa external-lsa
 !
router ospfv3 65555
 stub-router router-lsa v6-bit
  always

Save the changes:
RP/0/RSP0/CPU0:IOS-XR(config)#commit

 
Verify:
show ospf database
@ISIS
Increase ISIS metric
router isis XXXX
set-overload-bit
 
Save the changes:
RP/0/RSP0/CPU0:IOS-XR(config)#commit
