2. Add default 2 rules LowerCaseRule and RemoveTrailingSlashRule
3. Manually add selected lines
<rule name="LowerCaseRule1" stopProcessing="true">
<match url="[A-Z]" ignoreCase="false" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{REQUEST_METHOD}" matchType="Pattern" pattern="POST" ignoreCase="true" negate="true" />
</conditions>
<action type="Redirect" url="{ToLower:{URL}}" />
</rule>
<rule name="RemoveTrailingSlashRule1" stopProcessing="true">
<match url="(.*)/$" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_METHOD}" matchType="Pattern" pattern="POST" ignoreCase="true" negate="true" />
</conditions>
<action type="Redirect" url="{R:1}" />
</rule>

or you can add this lines
<rule name="LowerCaseRule1" stopProcessing="true">
<match url="[A-Z]" ignoreCase="false" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{REQUEST_METHOD}" pattern="GET" />
</conditions>
<action type="Redirect" url="{ToLower:{URL}}" />
</rule>
<rule name="RemoveTrailingSlashRule1" stopProcessing="true">
<match url="(.*)/$" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_METHOD}" pattern="GET" />
</conditions>
<action type="Redirect" url="{R:1}" />
</rule>
