Parsing file into helm template-CodePudding

I try parsing file

VAR1=https://com.dom
VAR2=abcd=efg=

by template

{{- range $path, $_ :=  $.Files.Glob $envPath }}
    {{- range split "\n" ($.Files.Get $path) }}
      {{- if . }}
        {{- $kv := splitList "=" . -}}
          {{- $k := first $kv}}
          {{- if contains "RAW_" $k }}
            {{- first $kv | replace "RAW_" "" | nindent 2}}: {{last $kv | quote }}
            {{ else}}
            {{- first $kv | nindent 2}}: {{last $kv | replace "'" "" | b64enc | quote }}
          {{-  end }}
  {{-  end }}
    {{- end }}
{{- end }}
{{- end }}

and got

data:
  VAR1: "aHR0cHM6Ly9jb20uZG9t"
  VAR2: ""

becouse splitList get last "=", but I want that splitList take only first "=" will take as seporator. note: base64 have "=" at your hashes.
