How to disable the timer job for "Database Statistics"

Question

I want to disable the database statistics timer job using the powershell, but I cant find the exact name of it in the list of timer jobs.
tried
Get-SpTimerjob to manually look for it Get-SPTimerJob SPDatabaseStatisticsJobDefinitionor and also looked for staadmin name job-database-statistics
I even tried to look for it in the list of timer job definitions for a web application with no luck.
I want to disable the timerjob, so that I can run proc_DefragmentIndices on sharepoint config and SharePoint admin databases.
SELECT DB_ID() AS [sharepoint_admincontent_cab0c190-db30-4f2c-8b71-504b81d2b5d1];
GO
SELECT * FROM sys.dm_db_index_physical_stats
    (1, NULL, NULL, NULL , 'DETAILED');
1 1131151075
1 1
CLUSTERED INDEX
IN_ROW_DATA 2
0 52.6315789473684
1 1131151075
1 1
CLUSTERED INDEX
IN_ROW_DATA 2
1 0
1 1131151075
2 1
NONCLUSTERED INDEX

Thank you Trevor, 
As per this blog (http://www.houberg.com/2008/05/16/sharepoint-database-indexes-and-statistics/) it seems like
Microsoft allows this (not explicitly though)
I ran the Health Analyzer rule  for "Databases used by SharePoint have fragmented Indexes" for all servers.
I am still seeing a lot of cluster and non clustered indexes having avg_fragmentation_in_percent
 > 60%.
SELECT * FROM sys.dm_db_index_physical_stats (7, NULL, NULL, NULL , 'DETAILED');
I finally thought that I should rebuild the indexes to fix the issue, but please suggest if that is not the correct approach to resolve the high fragmented indexes.
thanks
Nate
