My touch is working fine with philz but screen has to be turn off/on to activate touch on TWRP every time.

I´m not sure if I catched what you mean with touchpad maybe touch panel?
If this is your issue then is not in the kernel itself but in the kind of panel that some manufacturers use on some devices by i.e. Xiaomi uses on a same model (not even on different) atleast three kinds of display; Tiamma, BOE, EBBG and maybe more. The reason? some of them are cheaper.
Developers of TWRP use the only kernel released for a device and given that stock recovery doesn´t need a touch screen enabled and the drivers from the source are not 100% compatible with these then they´re not perfectly adapted to it. It could be that on new releases of TWRP touch screen won´t respond at all. This could be solved using the old drivers but this need a TWRP built from the source or a good dev to edit the exact/s binary line/s when drivers are loaded and knowing which driver your device is using.
If there´s not kernel sources available for your device and TWRP was ported from other similar device then search from another that has atleast two kinds of panel and that this TWRP has been made for both kinds of them.
Download an app like Aida64 and look at Display section to give you an idea, similarly you can find it using adb commands

So Step by Step Procedures Please if anyone can help me thanks in Advance
With a locked bootloader you can´t spoof official signature from OPPO to flash it through by i.e Qualcomm Downloader Tool, in the case the tool starts the flashing process most likely will end with error and this could brick your device.
You theoretically could do it by using a tool that accepts EDL mode like QPST/Qfil but only an owner that tried can confirm you for sure. It works on some devices but you´ll need some skills to send device to this mode using testpoint method.
If OPPO brings support to unlock bootloader then you can do it easily via fastboot.
