How can I prevent additional newlines with set-content while keeping existing ones when saving in UTF8?

Set-Content appends a newline (line break, CRLF) at the end of my file

I have a snippet of code which gets the content of each file and will replace values within it if it matches my variable list.
The code works fine. However, after the scan it's leaving a blank line at the end of the file which I do not want to happen.
# From the location set in the first statement
# Recurse through each file in each folder that has an extension defined
# in-Include
$configFiles = Get-ChildItem $Destination -Recurse -File -Exclude *.exe,*.css,*.scss,*.png,*.min.js
foreach ($file in $configFiles) {
Write-Host $file.FullName
# Get the content of each file and search and replace values as defined in
# the searc/replace table
$fileContent = Get-Content $file.FullName
$fileContent | ForEach-Object {
$line = $_
$lookupTable.GetEnumerator() | ForEach-Object {
# [Regex]::Escape($_.Key) treats regex metacharacters in the search
# string as string literals
if ($line -match [Regex]::Escape($_.Key)) {
$line = $line -replace [Regex]::Escape($_.Key), $_.Value
}
}
$line
} | Set-Content $file.FullName
}
I've tried adding:
Set-Content $file.FullName -NoNewline
This just puts everything in the file on one line.
Some files will already have a blank line at the end which I want to stay the same, so I can't just remove the last line of every file.
How do I stop this script from adding a new line once finished scanning?
$lookuptable for reference:
$lookupTable = #{
'Dummy' = $ReplacementValue
'Dummy2' = $ReplacementValue
}
