Powershell: how to override template parameters of an existing "user experience monitor"?

i found this SQL-Statement that do this job:

begin tran
if @ComponentId <= 0
begin
insert into APM_Component (Name, ShortName, ComponentType, ApplicationID, TemplateID, ComponentOrder, IsDisabled)
select @Name, @ShortName, @ComponentType, @ApplicationId, @CompTemplateId, @ComponentOrder, @IsDisabled
select @ComponentId = SCOPE_IDENTITY()
end
else
begin
update APM_Component
set
Name = @Name,
ShortName = @ShortName,
ComponentType = @ComponentType,
ApplicationID = @ApplicationId,
TemplateID = @CompTemplateId,
ComponentOrder = @ComponentOrder,
IsDisabled = @IsDisabled
where ID = @ComponentId
end
select @ComponentId
DECLARE @externalSettingIds table
(
ID int NOT NULL,
ExternalSettingID int NOT NULL
)
DELETE FROM APM_ExternalSetting
WHERE ID IN
(
SELECT Value
FROM APM_ComponentSetting
WHERE ComponentID = @ComponentId
AND ValueType = @ExternalValueType
)
DELETE FROM APM_ComponentSetting WHERE ComponentID = @ComponentId
MERGE INTO APM_ExternalSetting AS target
USING (SELECT ID,
[Key],
Value,
ValueType,
Required
FROM @componentSettings
WHERE ValueType = @ExternalValueType) AS source
ON 1 = 0
WHEN NOT MATCHED BY TARGET THEN
INSERT (Setting) VALUES ( source.value)
OUTPUT source.ID, INSERTED.ID AS ExternalSettingID INTO @externalSettingIds;
INSERT INTO APM_ComponentSetting (ComponentID, [Key], Value, ValueType, Required)
SELECT @ComponentId,
setting.[Key],
CASE WHEN extSetting.ExternalSettingID IS NULL
THEN setting.Value
ELSE CAST(extSetting.ExternalSettingID AS nvarchar(max))
END,
setting.ValueType,
setting.Required
FROM @componentSettings setting
LEFT JOIN @externalSettingIds extSetting
ON setting.ID = extSetting.ID commit tran ',N'@IsDisabled bit,@Name nvarchar(125),@ShortName nvarchar(125),@ComponentType int,@ApplicationId int,@CompTemplateId bigint,@ComponentOrder int,@componentSettings [APM_ComponentSettingTableType] READONLY,@ComponentId bigint,@ExternalValueType int'

But, it doesn't exist a supported way to script my requirement in powershell?
