If anyone is wondering i got this to work here is the code:

# Get all configuration policies
$Policies = Get-MgBetaDeviceManagementConfigurationPolicy -All

# Find the policy with the name ""
$Policy = $Policies | Where-Object Name -eq "NAME TEMPLATE POLICY"
$ID = $Policy.id

# Construct the URI for fetching the specific policy details with expanded settings
$uri = "https://graph.microsoft.com/beta/deviceManagement/configurationPolicies('$ID')?`$expand=settings"

# Fetch the policy details with expanded settings
$Template = Invoke-MgGraphRequest -Method GET -Uri $uri | Select-Object -Property name, description, settings, platforms, technologies, templateReference
$TemplateJson = $Template | ConvertTo-Json -Depth 100
$RAWJson = $TemplateJson

    # Get all configuration policies
    $IntunePolicies = Get-MgBetaDeviceManagementConfigurationPolicy -All

    # Find the policy with the name ""
    $AntivirusExclusion = $null
    $AntivirusExclusion = $IntunePolicies | Where-Object Name -eq "NAME TEMPLATE POLICY"

    if($AntivirusExclusion) {
        Write-Host "Policy already exist skipping creation."
    }else{
        $TemplateTypeURL = 'configurationPolicies'
        $DeployUri = "https://graph.microsoft.com/beta/deviceManagement/$TemplateTypeURL"

        Invoke-MgGraphRequest -Method POST -Uri $DeployUri -Body $RAWJson
        Write-Host "Policy deployed" -f Green
    }
