Default install php is 8.0 but php command is 8.1 how to fix it?

Question

The default install script

wget -qO weby qrok.es/wy && sudo bash weby

is php 8.0 but it install php8.1 too . The problem is php command in bin dir is link with php8.1 so when I install new custom php extension like php-brotli it will install for php8.1 and cant use for php8 . The system always install new ext for php8.1 not 8.0 . I just want fully remove php 8.1 in my system but I dont know how .

Please don't install 2 php version in one system it make many bug when use php command
