My htaccess

RewriteEngine On


RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]


RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]


RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^(.*)$ /$1.html



RewriteCond %{REQUEST_URI} !^subdom/
RewriteCond %{REQUEST_URI} !^/subdom/
RewriteCond %{HTTP_HOST} ^(www\.)?(.*)\.([^\.]*)\.([^\.]*)$
RewriteCond %{DOCUMENT_ROOT}/subdom/%2 -d
RewriteRule (.*) subdom/%2/$1 [DPI]


RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^domains/[^/]+/(.+[^/])$ /$1/ [R]

RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^subdom/[^/]+/(.+[^/])$ /$1/ [R]

This dont work

RewriteCond %{QUERY_STRING} ^page=([^&]+)$
RewriteRule ^index\.php$ %1? [R=301,L,NE]
RewriteRule ^([^/]+)\.html index.php?page=$1 [L,QSA]

And this not working to

RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f


RewriteRule ^([^/]+)/([^/]+)/(.+)$ index.php?lang=$1&page=$2 [L,QSA]
RewriteRule ^([^/]+)/(.+)$ index.php?lang=$1 [L,QSA

I need make from this https://mypage.com/index.php?page=my-page and https://mypage.com/index.php?lang=en&page=my-page

this https://mypage.com/my-page/ and https://mypage.com/en/my-page/

With your shown sample, please try following htaccess. Added OP's already existing rules here(I removed OP's rule RewriteCond %{REQUEST_URI} !^subdom/ since REQUEST_URI variable always starts from / so need for this rule) and appended by suggested rules in it. Please make sure you clear your browser cache before testing your URLs.
