Combine mod_rewrite rules for Craft CMS 3 with cache busting - regex

Question

My Craft CMS 3 project has the following rewrite_rule in the /web .htaccess.
<IfModule mod_rewrite.c>
RewriteEngine On
# Send would-be 404 requests to Craft
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/(favicon\.ico|apple-touch-icon.*\.png)$ [NC]
RewriteRule (.+) index.php?p=$1 [QSA,L]
</IfModule>
Trying to implement cache busting has described here however struggling to combine the existing and proposed rewrite_rules.

This is the cache busting rule I need to add.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*?\/)*?([a-z\.\-]+)(\d+)\.(bmp|css|cur|gif|ico|jpe?g|js|png|svgz?|webp|webmanifest)$ $1$2$4 [L]
</IfModule>

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*?\/)*?([a-z\.\-]+)(\d+)\.(bmp|css|cur|gif|ico|jpe?g|js|png|svgz?|webp|webmanifest)$ $1$2$4 [NC]
# Send would-be 404 requests to Craft
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/(favicon\.ico|apple-touch-icon.*\.png)$ [NC]
RewriteRule (.+) index.php?p=$1 [QSA,NC]

RewriteCond %{HTTP:X-Forwarded-Port} !=443
