What I want to do is just delete some lines from a text file, I know it's easy using copy and redirect function, but what I have to do is edit this file (delete the lines) directly, as new lines may be added to the text file during this period. Can AIX do this ?

sysctl.d
SYSCTL.D(5) sysctl.d SYSCTL.D(5)NAME
sysctl.d - Configure kernel parameters at boot
SYNOPSIS
/etc/sysctl.d/*.conf
/run/sysctl.d/*.conf
/usr/lib/sysctl.d/*.conf
DESCRIPTION
systemd uses configuration files from the above directories to configure sysctl(8) kernel parameters to load during boot.
CONFIGURATION FORMAT
The configuration files should simply contain a list of variable assignments, separated by newlines. Empty lines and lines whose first
non-whitespace character is # or ; are ignored.
Note that both / and . are accepted as separators in sysctl variable names.
Each configuration file is named in the style of <program>.conf. Files in /etc/ overwrite files with the same name in /usr/lib/. Files in
/run overwrite files with the same name in /etc/ and /usr/lib/. Packages should install their configuration files in /usr/lib/, files in
/etc/ are reserved for the local administration, which possibly decides to overwrite the configurations installed from packages. All files
are sorted by filename in alphabetical order, regardless in which of the directories they reside, to ensure that a specific configuration
file takes precedence over another file with an alphabetically later name.
EXAMPLE
Example 1. /etc/sysctl.d/domain-name.conf example:
# Set kernel YP domain name
kernel.domainname=example.com
