Combine RewriteRules in .htaccess so that a specific query parameter is ignored

I'm trying to write some RewriteRules so that when a request contains a specific query parameter, let's call it foo, it is ignored (removed) completely. The reason for this is that I need to use foo internally in another RewriteRule so that I can pass information to my front controller. If foo would already exist, the application wouldn't work as intended. I tried multiple solutions, for example this one, but that doesn't do what I'd like to achieve. So far, I tried the following:

<IfModule mod_rewrite.c>
RewriteEngine On

# Remove possible existing query parameter called 'foo'
RewriteCond %{QUERY_STRING} ^(.*)&?foo=[^&]+&?(.*)$ [NC]
RewriteRule ^(.*)$ /$1?%1%2 [R=301,L]

# Lead every page/API request to index.php
RewriteCond $1 !\.(svg|jpg|png|webp|ico|css|js|ttf|woff|woff2)$
RewriteRule ^(.*)$ index.php?foo=$1 [L,QSA]

</IfModule>

Basically, every request which doesn't end with one of the listed file extensions should be passed to my front controller. Without the lines 5 and 6 everything works fine as long as no foo query parameter exists in the original request.

Is there a way to just remove the foo parameter without affecting the other RewriteRule (or simply to override it in the second part)? Thanks in advance!

Edit

Just to clarify a few things: In my application, the front controller is a PHP script that takes the rewritten GET parameter foo, which contains the originally requested URL. However, if the user adds foo to the request, I have to make sure this is not the foo parameter that gets passed to the front controller as the app wouldn't work properly then.

For example: If the client requests https://example.com/something?foo=123&bar=456, the request should be redirected to https://example.com/something?bar=456 (or alternatively not redirected at all) and the query parameter foo in line 9, which is intended for my front controller only, should be https://example.com/something with bar not being changed. Unfortunately, the above code wont't do this. Instead, I'm redirected to https://example.com/index.php?bar=456. I guess the solution is actually pretty simple, but I'm not able to find out how to do it.

Could you please try following. please make sure you clear your browser cache before testing your URLs. Considering here you need everything after & in query string to be passed in rewritten URL here. Added 2 existing rules from OP's htaccess file and changed place for https rule moved it to very first place.

RewriteEngine ON
##From OP's comments adding these here, http --> https should come first.
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [R=301,L]

# Remove possible existing query parameter called 'foo'
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ^(.*)&?foo=[^&]+&?(.*)$
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI}?%1%2 [NE,L]

# Lead every page/API request to index.php
RewriteCond $1 !\.(svg|jpg|png|webp|ico|css|js|ttf|woff|woff2)$
RewriteRule ^(.*)$ index.php?foo=$1 [L,QSA]
