I am tidying up my print PDF services (long overdue).  But I can't find a way to delete the two "Save to..." PDF services:

[![PDf Services][1]][1]

They were created by me with Automator probably under [Catalina][2] and placed in `/Library/PDF Services`.  Since then macOS upgrades have moved them into `/System/Library/PDF Services` which is part of the read-only file system.  Their creation and modification dates are when I installed [macOS 13.1][3] (Ventura), even though this is not strictly correct by two or three years!

Here they are in [Terminal][4]:

```
gilby@Beth/System/Library/PDF Services% ls -lah@e
total 80
drwxr-xr-x    5 root  wheel   160B  2 Dec 22:37 .
drwxr-xr-x  146 root  wheel   4.6K  2 Dec 22:37 ..
-rwxr-xr-x    1 root  wheel   164K  2 Dec 22:37 Save to Web Receipts
-rwxr-xr-x    1 root  wheel   164K  2 Dec 22:37 Save to iCloud Drive
lrwxr-xr-x    1 root  wheel    29B  2 Dec 22:37 Send in Mail -> /System/Applications/Mail.app
```

And when I attempt to delete and override the restricted status I get the error that they are in the *read-only* file system:

```
gilby@Beth/System/Library/PDF Services% sudo rm /System/Library/PDF\ Services/Save\ to\ Web\ Receipts
override rwxr-xr-x root/wheel restricted,compressed for /System/Library/PDF Services/Save to Web Receipts? Y
rm: /System/Library/PDF Services/Save to Web Receipts: Read-only file system
g
```

I do have [SIP][5] disabled:

```
gilby@Beth/System/Library/PDF Services% csrutil status
System Integrity Protection status: disabled.
```

How do I delete them?

I am running macOS 13.1 (upgraded three times from macOS 10.15 Catalina), on a 2019 iMac.
