Since you already got the build definition. Then you just need to use Definitions - Update Rest API to update
PUT https://dev.azure.com/{organization}/{project}/_apis/build/definitions/{definitionId}?secretsSourceDefinitionId={secretsSourceDefinitionId}&secretsSourceDefinitionRevision={secretsSourceDefinitionRevision}&api-version=5.0
In the request body, there is a BuildTrigger represents a trigger for a buld definition. Which is an array[]. It contain the schedule
string : A build should be started on a specified schedule whether or not changesets exist.
Body sample for your reference:

As how to invoke Rest API in powershell, there are multiple samples in google, you could also take a look at this one:
$body = '
{
...
}
'
$bodyJson=$body | ConvertFrom-Json
Write-Output $bodyJson
$bodyString=$bodyJson | ConvertTo-Json -Depth 100
Write-Output $bodyString
$user="name"
$token="PAT"
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user,$token)))
$Uri = "rest api url"
$buildresponse = Invoke-RestMethod -Method Post -UseDefaultCredentials -ContentType application/json -Uri $Uri -Body $bodyString -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}
write-host ....
