Had a similar Sony TV with the same feet as yours, needed to replace feet for a stand that would accommodate a centre speaker underneath.
Click the link below to see the stand that I bought for my TV (first on list),
https://www.amazon.co.uk/s?k=TV+table+top+stands&crid=3F6UYGAQDW0CS&sprefix=tv+table+top+stands%2Cap...
Check the whole list to find a stand that you think is suitable for your needs.
Make sure the stand can take the weight of your TV. Also that it is suitable for the width and height of your TV.
If you are placing any centre speaker or soundbar beneath the TV check that the dimensions of the stands base
will accommodate this and the height adjustment on the stand will be enough for clearance.
The stand will attach to the VESA mount screw holes on the back of the TV another thing you will need to check
that both are compatible.
To find the dimensions, weight and VESA mount screw hole dimensions of your TV click on the link below to the Specifications for your TV,

If buying the Bontec stand at the top of the list it arrives ready for assembly this takes a little time but comes with full instructions and the Allen keys necessary, you will need a Philips screwdriver.
When attaching the TV to the stand please remember to take the original Sony feet off the TV, I have seen some pictures of TVs on stands but with the original feet still attached, it is not a good look.
