How to change library lookup paths on Debian: Unable to load dynamic library 'gd.so'

I have 2 server A, B.Server A works properly, server B doesn't.

On Server B, when I perform the command

php7.4 -d display_startup_errors=on -d display_errors=on

I get the following error:

Warning: PHP Startup: Unable to load dynamic library 'gd.so' (tried: /usr/lib/php/20190902/gd.so (libdav1d.so.4: cannot open shared object file: No such file or directory), /usr/lib/php/20190902/gd.so.so (/usr/lib/php/20190902/gd.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

On server A, everything is fine, when I perform the command above.

On server A, when I perform lsof /usr/lib/php/20190902/gd.so

I get the following output:

On server B, I dont get any output, when i perform the command above.

None of the 2 server actually have a file called libdav1d.so.4 but they both have a file called libdav1d.so.6

On server A, when I perform the command

ldd /usr/lib/php/20190902/gd.so | grep libdav

I get the output

libdav1d.so.6 => /lib/x86_64-linux-gnu/libdav1d.so.6 (0x00007fb671fbb000)

On Server B, when I perform the command above, I get the following output:

libdav1d.so.4 => not foundlibdav1d.so.6 => /lib/x86_64-linux-gnu/libdav1d.so.6 (0x00007fdc1402f000)

My question is:

1. From where does server B get the information to look for libdav1d.so.4? Can I change the entry somewhere?
